A large effect has been found of + the mean stress on the fatigue strength depending on the chemical + composition of the materials and of crystallisation transformation if it + appears. The crack growth rate is studied using linear fracture + mechanics as proposed earlier (Rivlin RS, Thomas AG. Rupture of rubber: + I. Characteristic energy for tearing. J Polymer Sci 1953;10(3):291). In + this case, the strain energy release rate G is substituted for the + concept of tearing energy T. The application of fracture mechanics to + elastomers generates some difficulties because of the important + deformability. In order to apply a tens ion-compression loading a thick + edge notched specimen is recommended with two lateral grooves (W=150 mm, + B=25 mm). For low values of DeltaT, a threshold can de defined depending + on the R ratio. It is shown that for a high R ratio the fatigue crack + would not propagate if the crystallisation transformation is high. In + contrast, if R=-1, the threshold disappears. A finite element simulation + of stresses and strains is presented in order to get a better + explanation of the experimental results.

This also represents a challenge from materials + science and fracture mechanics viewpoints. Bone has a complex, + hierarchical structure with characteristic features ranging from + nanometer to macroscopic dimensions; it is therefore significantly more + complex than most engineering materials. Nevertheless, by examining the + micro-/nanostructural changes accompanying the process of aging using + appropriate multiscale experimental methods and relating them to + fracture mechanics data, it is possible to obtain a quantitative picture + of how bone resists fracture. As human cortical bone exhibits rising ex + vivo crack-growth resistance with crack extension, its fracture + toughness must be evaluated in terms of resistance-curve (R-curve) + behavior. While the crack initiation toughness declines with age, the + more striking finding is that the crack-growth toughness declines even + more significantly and is essentially absent in bone from donors + exceeding 85 years in age. To explain such an age-induced deterioration + in the toughness of bone, we evaluate its fracture properties at + multiple length scales, specifically at the molecular and nano + dimensions using vibrational spectroscopies, at the microscale using + electron microscopy and hard/soft x-ray computed tomography, and at the + macroscale using R-curve measurements.

It is + mostly made of microscopic ceramic tablets densely packed and bonded + together by a thin layer of biopolymer. The hierarchical microstructure + of this biological material is the result of millions of years of + evolution, and it is so well organized that its strength and toughness + are far superior to the ceramic it is made of.

One + improvement, proposed here, is that, for quasibrittle structures of + positive geometry, the understrength factors for structural safety + cannot be constant but must be increased with structures size. The + statistics of safety factors has so far been generally regarded as + independent of mechanics, but further progress requires the cumulative + distribution function (cdf) to be derived from the mechanics and physics + of failure. To predict failure loads of extremely low probability (such + as 10(-6) to 10(-7)) on which structural design must be based, the cdf + of strength of quasibrittle structures of positive geometry is modelled + as a chain (or series coupling) of representative volume elements (RVE), + each of which is statistically represented by a hierarchical model + consisting of bundles (or parallel couplings) of only two long + sub-chains, each of them consisting of sub-bundles of two or three long + sub-sub-chains of sub-sub-bundles, etc., until the nano-scale of atomic + lattice is reached. Based on Maxwell-Boltzmann distribution of thermal + energies of atoms, the cdf of strength of a nano-scale connection is + deduced from the stress dependence of the interatomic activation energy + barriers, and is expressed as a function of absolute temperature T and + stress-duration c (or loading rate 1/tau). A salient property of this + cdf is a power-law tail of exponent 1. It is shown how the exponent and + the length of the power-law tail of cdf of strength is changed by series + couplings in chains and by parallel couplings in bundles consisting of + elements with either elastic-brittle or elastic-plastic behaviors, + bracketing the softening behavior which is more realistic, albeit more + difficult to analyze. The power-law tail exponent, which is 1 on the + atomistic scale, is raised by the hierarchical statistical model to an + exponent of m = 10 to 50, representing the Weibull modulus on the + structural scale. Its physical meaning is the minimum number of cuts + needed to separate the hierarchical model into two separate parts, which + should be equal to the number of dominant cracks needed to break the + RVE. Thus, the model indicates the Weibull modulus to be governed by the + packing of inhomogeneities within an RVE. On the RVE scale, the model + yields a broad core of Gaussian cdf (i.e., error function), onto which a + short power-law tail of exponent m is grafted at the failure probability + of about 0.0001-0.01. The model predicts how the grafting point moves to + higher failure probabilities as structure size increases, and also how + the grafted cdf depends on T and tau. The model provides a physical + proof that, on a large enough scale (equivalent to at least 500 RVEs), + quasibrittle structures must follow Weibull distribution with a zero + threshold. The experimental histograms with kinks, which have so far + been believed to require the use of a finite threshold, are shown to be + fitted much better by the present chain-of-RVEs model. For not too small + structures, the model is shown to be essentially a discrete equivalent + of the previously developed nonlocal Weibull theory, and to match the + Type I size effect law previously obtained from this theory by + asymptotic matching. The mean stochastic response must agree with the + cohesive crack model, crack band model and nonlocal damage models. + The chain-of-RVEs model can be verified and calibrated from the mean + size effect cure, as well as from the kink locations on experimental + strength histograms for sufficiently different specimen sizes.

However when the crack + is relatively small, it is difficult to identify the presence of the + crack by a mere observation of the vibration response data. A new + approach for crack detection in beam-like structures is presented and + applied to cracked simply supported beams in this paper.

It + provides a more accurate estimate of the variances at each scale and + facilitates the identification of salient features in a signal, + especially for recognising noise or signal rupture. It is well known + that the mode shape of a beam containing a small crack is apparently a + single smooth curve like that of an uncracked beam. However, the mode + shape of the cracked beam actually exhibits a local peak or + discontinuity in the region of damage. Therefore, the mode shape + `signal' of a cracked beam can be approximately considered as that of + the uncracked beam contaminated by `noise', which consists of response + noise and the additional response due to the crack. Thus, the modal data + can be decomposed by SWT into a smooth curve, called the approximation + coefficient, and a detail coefficient. The difference of the detail + coefficients of the two new signal series includes crack information + that is useful for damage detection. The modal responses of the damaged + simply supported beams used are computed using the finite element + method. For real cases, mode shape data are affected by experimental + noise. Therefore, mode shape data with a normally distributed random + noise are also studied. The results show that the proposed method has + great potential in crack detection of beam-like structures as it does + not require the modal parameters of an uncracked beam as a baseline for + crack detection.

The other + objective of this work was to assess the impact of desaturation on the + hydraulic head profile measured around the tunnel. One section was + selected per drift. Two boreholes were drilled for each section: one + parallel and one inclined (45 degrees) with respect to the bedding. For + each borehole, we performed on-site drill core mapping, petrophysical + measurements, pneumatic and hydraulic tests by means of a Modular + Mini-Packer System (MMPS). Results indicate that the EDZ around drifts + is mainly a combination of unloading joints, mimicking the drift shape, + and of desaturation cracks, parallel to the bedding. The EDZ extension + around the tunnel is twice to three times that of the drifts of 1996 and + 2003 and is essentially composed of unloading joints resulting from the + mechanical response of the rock. The masonery covering the tunnel walls + is assumed to have protected the rock from seasonal variations of air + humidity, thus limiting (without excluding) the formation of + desaturation cracks.

A decrease of 50\%, for crack + densities larger than 1, 80\% for crack densities larger than 5 is + predicted, in close agreement with Our observed experimental variation + of K(1C). At the microscale, this can be interpreted by the fact that + the main fracture is strongly interacting with the pre-existing + microcrack fabric. These combined experimental and modeling results + illustrate the importance of understanding the details of how the rock + microstructure is changing in response to an external stimulus, ill + order to predict the simultaneous evolution of physical and mechanical + properties of rock.

The model comprises four essential + features: (i) micro-crack extension rates based on stress-intensity + calculations and a crack growth law, (ii) the effect of the crack + density on the stiffness, inclusive of crack closure, (iii) plasticity + at high confining pressures, and (iv) initial flaws that scale with the + grain size. Predictions of stress/strain responses for a range of stress + states demonstrate that the model captures the transition from + deformation by micro-cracking at low triaxiality to plastic slip at high + triaxialities. Moreover, natural outcomes of the model include dilation + (or bulking) upon micro-cracking, as well as the increase in the shear + strength of the damaged ceramic with increasing triaxiality. Cavity + expansion calculations are used to extract some key physics relevant to + penetration. Three domains have been identified: (i) quasi-static, where + the ceramic fails due to the outward propagation of a compression damage + front, (ii) intermediate velocity, where an outward propagating + compression damage front is accompanied by an inward propagating tensile + (or spallation) front caused by the reflection of the elastic wave from + the outer surface and (iii) high velocity, wherein plastic deformation + initiates at the inner surface of the shell followed by spalling within + a tensile damage front when the elastic wave reflects from the outer + surface.

In order to assess potentially + beneficial effects of plastic property gradients in tribological + applications, it is essential first to develop a comprehensive and + quantitative understanding of the effects of yield strength and strain + hardening exponent on contact deformation under the most fundamental + contact condition: normal indentation. To date, however, systematic and + quantitative studies of plasticity gradient effects on indentation + response have not been completed. A comprehensive parametric study of + the mechanics of normal indentation of plastically graded materials was + therefore undertaken in this work by recourse to finite element method + (FEM) computations. On the basis of a large number of computational + simulations, a general methodology for assessing instrumented + indentation response of plastically graded materials is formulated so + that quantitative interpretations of depth-sensing indentation + experiments could be performed. The specific case of linear variation in + yield strength with depth below the indented surface is explored in + detail. Universal dimensionless functions are extracted from FEM + simulations so as to predict the indentation load versus depth of + penetration curves for a wide variety of plastically graded engineering + metals and alloys for interpretation of, and comparisons with, + experimental results. Furthermore, the effect of plasticity gradient on + the residual indentation pile-up profile is systematically studied. The + computations reveal that pile-up of the graded alloy around the + indenter, for indentation with increasing yield strength beneath the + surface, is noticeably higher than that for the two homogeneous + reference materials that constitute the bounding conditions for the + graded material.

The natural frequencies of a damaged + beam with a traversing auxiliary mass change due to change in the + inertia of the beam as the auxiliary mass is traversed along the beam, + as well as the point-to-point variations in the flexibility of the beam. + Therefore the auxiliary mass call enhance the effects of the crack on + the dynamics of the beam and, therefore, facilitate the identification + and location of damage in the beam. That is, the auxiliary mass can be + used to probe the dynamic characteristic of the beam by traversing the + mass from one end of the beam to the other. However, it is impossible to + obtain accurate modal frequencies by the direct operation of the fast + Fourier transform (FFT) of the response data of the structure because + the frequency spectrum can be only calculated from limited sampled time + data which results in the well-known leakage effect. SCCM is identical + to the energy centrobaric correction method (ECCM) which is a practical + and effective method used in rotating mechanical fault diagnosis and + which resolves the shortcoming of FFT and can provide high accuracy + estimate of frequency, amplitude and phase. In the present work, the + modal responses of damaged simply supported beams with auxiliary mass + are computed using the finite element method (FEM). The graphical plots + of the natural frequencies calculated by SCCM versus axial location of + auxiliary mass are obtained.

The experimental + configuration used in our work permitted soft recovery of the samples to + allow a careful examination of the fractured samples along with + real-time measurements of the sample free-surface velocity (FSV) + histories. Tensile loading was preceded by elastic compressive loading + to peak stresses in the 3.6 to 6.0 GPa range. Tensile damage in the + recovered samples was examined using optical and electron microscopy. + The microscopy results showed that the BAA samples exhibit a brittle + behavior (as a glass) at the macroscopic level and a ductile behavior + (as a metal) at the microscopic level; in addition, corrugations and + bumps are observed at the nanoscale. The observed fracture morphologies + are related to three key features present in our spall experiments: + preceding compressive stress (3.6-6.0 GPa), high tensile loading rate + (similar to 10(6)/s), high mean tensile stress (similar to 2.3 GPa); and + are intrinsically related to the amorphous glassy structure of the BAAs + (free volume content).

Consequently, the observed surface morphology + results from brittle cleavage, causing an increased damage localization + in the recovered samples spalled at higher stresses.

The high + tensile loading rate is proposed to be responsible for cracking by + multiple shear band propagation and interception, rendering the observed + serrated surface morphology. Finally, we proposed that the corrugations + are created due to a succession of arrest and propagation of mode I + cracks. A subsequent dilatation, due to the effect of the tensile mean + stress, caused the corrugations to evolve to bump-type features with + sizes in the range of 10-100 nm.

However, + the numerical simulation of failure due to fracture based on sharp crack + discontinuities may suffer in situations with complex crack topologies. + This can be overcome by a diffusive crack modeling based on the + introduction of a crack phase field. In this work, we develop a + framework of diffusive fracture in piezoelectric solids. We start our + investigation with the definition of a crack surface functional of the + phase field that 1 converges for vanishing length-scale parameter to a + sharp crack topology. This functional provides the basis for the + definition of suitable dissipation functions which govern the evolution + of the crack phase field. Based on experimental results available in the + literature, we suggest a non-associative dissipative framework where the + fracture phase field is driven by the mechanical part of the coupled + electromechanical driving force. This accounts for a hierarchical view + that considers (i) the decrease of stiffness due to mechanical rupture + as the primary action that is followed by (ii) the decrease of electric + permittivity due to the generated free space. The proposed definition of + mechanical and electrical parts of the fracture driving force follows in + a natural format from a kinematic assumption, that decomposes the total + strains and the total electric field into energy-enthalpy-producing + parts and fracture parts, respectively. Such an approach allows the + insertion of well-known anisotropic piezoelectric storage functions + without change. We end up with a three-field-problem that couples the + displacement with the electric potential and the fracture phase field. + The latter is governed by a micro-balance equation, which appears in a + very transparent form in terms of a history field containing a maximum + fracture source obtained in the time history of the electromechanical + process. This representation allows the construction of a very robust + algorithmic treatment based on a operator split scheme, which + successively updates in a typical time step the history field, the crack + phase field and finally the two piezoelectric fields.

The asphalt + binder was then characterized using the Superpave (TM) rotational + viscosity, dynamic shear modulus, and direct tension test. The + rotational viscosity results indicate that the addition of the two types + of nanoclay, Nanoclay A and Nanoclay 8, increased the rotational + viscosity by an average of 41\% and 112\%, respectively, across test + temperatures 80, 100, 130, 135, 150 and 175 degrees C. It was found that + the dynamic shear complex modulus (G{*}) value increases significantly + across a range of testing temperatures (from 13 to 70 degrees C) and + loading frequencies (0.01-25 Hz). With 2\% Nanoclay A reinforcement in + the asphalt binder, the complex shear moduli generally increased by 66\% + while the 4\% Nanoclay A reinforcement in the asphalt binder generally + increased the shear complex moduli by 125\%. The 2\% and 4\% Nanoclay B + increased the shear complex moduli by 184\% and 196\%, respectively. In + terms of direct tension strength, the use of Nanoclay A and Nanoclay B + reduced the strain failure rate of the original binder while the secant + or direct tension moduli showed increase with the addition of the + nanoclays. In furtherance of this research, nanoclay-modified asphalt is + being tested at percentages higher than 4\% to underscore the fact that + nanoclays may have the potential to reduce rutting and cracking.

Its characterization is a + pre-requisite to understanding and unraveling the complexities of + crustal evolution and dynamics. The preferential chemical interaction + between pore fluids and strained atomic bonds at crack tips, a mechanism + known as stress corrosion, allows rock to fail under a constant stress + that is well below its short-term strength over an extended period of + time: a process known as brittle creep. Here we present the first + experimental measurements of brittle creep in a basic igneous rock (a + basalt from Mt. Etna volcano) under triaxial stress conditions. Results + from conventional creep experiments show that creep strain rates are + highly dependent on the level of applied stress (and can be equally well + fit by a power law or an exponential law): with a 20\% increase in + stress producing close to three orders of magnitude increase in creep + strain rate. Results from stress-stepping creep experiments show that + creep strain rates are also influenced by the imposed effective + confining pressure. We show that only part of this change can be + attributed to the purely mechanical influence of an increase in + effective pressure, with the remainder interpreted as due to a reduction + in stress corrosion reactions; the result of a reduction in crack + aperture that restricts the rate of transport of reactive species to + crack tips. Overall, our results also suggest that a critical level of + crack damage is required before the deformation starts to accelerate to + failure, regardless of the level of applied stress and the time taken to + reach this point. The experimental results are discussed in terms of + microstructural observations and fits to a macroscopic creep law, and + compared with the observed deformation history at Mt. Etna volcano.

Thus, refined measurements of both + in-plane and out-of-plane displacements of the FRP strips are available. + A brief overview of the key contributions available in the scientific + literature on modeling the bond behavior of FRP strips glued to a + concrete substrate is firstly proposed. Then, a novel model based on + simulating the behavior of the FRP strip as a Bernoulli beam on a layer + of springs is formulated. It is aimed at determining the 2D displacement + field of the FRP strip during a pull-off test up to debonding which + actually occurs in a mixed fracture mode. The model is firstly + formulated within the linear range by assuming elastic behavior for the + above mentioned springs. The nonlinear behavior due to the cracking of + concrete beneath the adhesive interface is then introduced for + simulating the above mentioned experimental results. In particular, a + bilinear relationship is assumed between interface slips and shear + stresses, as is generally accepted within the scientific literature. + Furthermore, a damage model is considered for reducing the stiffness of + the transverse springs and simulating the crack propagation at the + adhesive-concrete interface. Although this is a simplified way of + modeling the nonlinear behavior of concrete in shear/tension, it results + in rather accurate simulations of the available experimental results. In + fact, it can simulate accurately the overall behavior observed in three + experimental tests on specimens characterized by significantly different + mechanical properties of the strip. Since the model assumes a small set + of mechanical parameters for describing the mechanical behavior of the + adhesive FRP-concrete interface and results in a reasonable small set of + equations, it can be easily employed for identifying the above mentioned + mechanical behavior indirectly. Other numerical models already available + in the scientific literature (especially those based on the theory of + finite elements) for simulating the 2D displacement field in the + debonding stage are generally based on much more equations and require a + much higher computational effort which makes impractical their use in an + indirect identification procedure like the one presented in this paper. + In fact, one of the main results of this study consists in determining + the distribution of normal (peeling) stresses throughout the + adhesive-to-concrete interface.

The + evolution of the dislocation density was modeled by considering the + generation and annihilation of single and dipole dislocations. In + addition to dislocation motion as a basis for creep deformation, there + are several other factors which determine the creep resistance of this + steel. Among these, the most significant are precipitate coarsening, + solid solutions depletion, and void/crack nucleation and growth. The + evolution of these mechanisms during creep deformation was accounted for + by introducing specific continuum damage terms. Creep tests were also + performed at several stress and temperature levels. The comparison of + the numerical model results with the experimental data showed + satisfactory agreement.

Here, we review the available experimental evidence for + brittle creep in crustal rocks, and the various models developed to + explain the observations. Laboratory experiments have shown that brittle + creep occurs in all major rock types, and that creep strain rates are + extremely sensitive to the environmental conditions: differential + stress, confining pressure, temperature and pore fluid composition.

In this review, the primary emphasis is relating the fatigue + crack initiation to the microstructure of the material. Many studies + have focused on this phenomenon over the years and the goal of this + paper is to put this work in perspective and encourage future work of + fatigue in polycrystals based on the material's microstructure. In order + to address fatigue, it is necessary to understand the mechanisms that + facilitate crack initiation. Slip irreversibilities exist in a material + and accumulate during fatigue loading. At the defect level, + irreversibilities are a result of dislocations: annihilating, + cross-slipping, penetrating precipitates, transmitting through grain + boundaries, and piling-up. These slip irreversibilities are the early + signs of damage during cyclic loading. The dislocations subsequently + form low-energy, stable structures as a means to accommodate the + irreversible slip processes and increasing dislocation density during + cyclic forward and reverse loading. The result is strain localizing in a + small region within the materials, i.e. persistent slip bands and + dislocation cells/bundles. Strain localization is a precursor to crack + initiation. This review paper will focus on experimental observations of + strain localization and the theory and numerical analysis of both slip + irreversibilities and low energy configuration defect structures. This + fundamental understanding is necessary to study persistent slip bands in + FCC metals and alloys including the appropriate characterization, + theory, and modeling. From this fundamental knowledge both + micromechanical and crystal plasticity models can be used to predict + crack initiation, which are also reviewed. Finally, this review ends + with a discussion of the future of fatigue modeling and experiments. (C) + 2012 Elsevier Ltd.

In this paper, we examine three different inverse algorithms + for solving the non-linear equations to predict the interface, + lengthwise location and size of delamination: direct of solution using a + graphical method, artificial neural network (ANN) and surrogate-based + optimization. The three inverse algorithms have been validated using + numerical data generated from the finite element model (FEM) of + delaminated beams and measured frequencies from modal testing conducted + on simply supported and cantilever carbon fiber reinforced beam + specimens.

For many volcanoes, + this basement can comprise thick sequences of carbonates that are prone + to significant thermally-induced alteration. These debilitating thermal + reactions, facilitated by heat from proximal magma storage volumes, + promote the weakening of the rock mass and likely therefore encourage + edifice instability. Such instability can result in slow, gravitational + spreading and episodic to continuous slippage of unstable flanks, and + may also facilitate catastrophic flank collapse. Understanding the + propensity of a particular sub-volcanic basement to such instability + requires a detailed understanding of the influence of high temperatures + on the chemical, physical, and mechanical properties of the rocks + involved. The juxtaposition of a thick carbonate substratum and magmatic + heat sources makes Mt Etna volcano an ideal candidate for our study. We + investigated experimentally the effect of temperature on two carbonate + rocks that have been chosen to represent the deep, heterogeneous + sedimentary substratum under Mt. Etna volcano. This study has + demonstrated that thermal-stressing resulted in a progressive and + significant change in the physical properties of the two rocks. + Porosity, wet (i.e., water-saturated) dynamic Poisson's ratio and wet + Vp/Vs ratio all increased, whilst P- and S-wave velocities, bulk sample + density, dynamic and static Young's modulus, dry Vp/Vs ratio, and dry + dynamic Poisson's ratio all decreased. At temperatures of 800 degrees C, + the carbonate in these rocks completely dissociated, resulting in a + total mass loss of about 45\% and the release of about 44 wt\% of CO2. + Uniaxial deformation experiments showed that high in-situ temperatures + (>500 degrees C) significantly reduced the strength of the carbonates + and altered their deformation behaviour. Above 500 C the rocks deformed + in a ductile manner and the output of acoustic emissions was greatly + reduced.

In + the beginning, the volume void fraction, based on conservation mass law, + is assumed as the first damage parameter, similar to Gurson's original + model. This volumetric damage contribution is able to capture spherical + void growth, which plays the main role in tensile loading condition. The + second damage parameter is proposed as a new shear mechanism, based on + geometrical and phenomenological aspects and is also a function of the + equivalent plastic strain, Lode angle and stress triaxiality. The shear + damage parameter is formulated independent of the volume void fraction + and requires a new nucleation of micro-defects mechanism to trigger the + shear growth contribution, and hence is able to capture elongated (and + rotation) void growth which is present in simple shear and combined + shear/tensile or shear/compression loading conditions. Furthermore, the + first and the second damage parameters are coupled in the yield function + in order to affect the hydrostatic stress and deviatoric stress + contributions, separately. In the first part of this paper, a review of + Gurson's model and its most famous version as GTN's model is done. After + that, the new contribution is presented and an implicit numerical + integration algorithm is determined, based on the operator split + methodology. The calibration strategy is discussed for determination of + material parameters. Numerical tests are performed for a butterfly + specimen using two types of materials (aluminum alloy 2024-T351 and + steel 1045) under ranges of stress triaxiality between-1/3 < eta < 1/3 + (shear/compression or shear/tensile).

The + ability to computationally predict the extent of damage and + compression-after-impact (CAI) strength of a composite structure can + potentially lead to the exploration of a larger design space without + incurring significant time and cost penalties. A high-fidelity + three-dimensional composite damage model, to predict both low-velocity + impact damage and CAI strength of composite laminates, has been + developed and implemented as a user material subroutine in the + commercial finite element package, ABAQUS/Explicit. The intralaminar + damage model component accounts for physically-based tensile and + compressive failure mechanisms, of the fibres and matrix, when subjected + to a three-dimensional stress state. Cohesive behaviour was employed to + model the interlaminar failure between plies with a bi-linear + traction-separation law for capturing damage onset and subsequent damage + evolution. The virtual tests, set up in ABAQUS/Explicit, were executed + in three steps, one to capture the impact damage, the second to + stabilize the specimen by imposing new boundary conditions required for + compression testing, and the third to predict the CAI strength. The + observed intralaminar damage features, delamination damage area as well + as residual strength are discussed. It is shown that the predicted + results for impact damage and CAI strength correlated well with + experimental testing without the need of model calibration which is + often required with other damage models.

Computational methods are employed to anticipate + the critical conditions of failure, yet they sometimes provide + inaccurate and misleading predictions. Challenge scenarios, such as the + one presented in the current work, provide an opportunity to assess the + blind, quantitative predictive ability of simulation methods against a + previously unseen failure problem. Rather than evaluate the predictions + of a single simulation approach, the Sandia Fracture Challenge relies on + numerous volunteer teams with expertise in computational mechanics to + apply a broad range of computational methods, numerical algorithms, and + constitutive models to the challenge. This exercise is intended to + evaluate the state of health of technologies available for failure + prediction. In the first Sandia Fracture Challenge, a wide range of + issues were raised in ductile failure modeling, including a lack of + consistency in failure models, the importance of shear calibration data, + and difficulties in quantifying the uncertainty of prediction {[}see + Boyce et al. (Int J Fract 186:5-68, 2014) for details of these + observations]. This second Sandia Fracture Challenge investigated the + ductile rupture of a Ti-6Al-4V sheet under both quasi-static and + modest-rate dynamic loading (failure in 0.1 s). Like the previous + challenge, the sheet had an unusual arrangement of notches and holes + that added geometric complexity and fostered a competition between + tensile- and shear-dominated failure modes. The teams were asked to + predict the fracture path and quantitative far-field failure metrics + such as the peak force and displacement to cause crack initiation. + Fourteen teams contributed blind predictions, and the experimental + outcomes were quantified in three independent test labs. Additional + shortcomings were revealed in this second challenge such as + inconsistency in the application of appropriate boundary conditions, + need for a thermomechanical treatment of the heat generation in the + dynamic loading condition, and further difficulties in model calibration + based on limited real-world engineering data. As with the prior + challenge, this work not only documents the `state-of-the-art' in + computational failure prediction of ductile tearing scenarios, but also + provides a detailed dataset for non-blind assessment of alternative + methods.}}, +Publisher = {{SPRINGER}}, +Address = {{VAN GODEWIJCKSTRAAT 30, 3311 GZ DORDRECHT, NETHERLANDS}}, +Type = {{Article}}, +Language = {{English}}, +Affiliation = {{Boyce, BL (Reprint Author), Sandia Natl Labs, POB 5800, Albuquerque, NM 87185 USA. + Boyce, B.

The principal + laminates damage forms encompassed delaminations occurring in composite + interlayers and on metal-composite interface, cracks in composite layers + and in lower layers of metal. Presented modelling of impact in fibre + metal laminates using VUMAT code enables the evaluation of their + structure damage and the selection of proper laminate configuration in + future in terms of their resistance to low-velocity impact.

Several configurations were considered in this + case. These include varying the number of fasteners in the joint region + as well as inclusion of bondline defects. Adhesive non-linear material + properties, fastener contacts and frictional forces were all included in + the three dimensional (3D) finite element (FE) models. The progressive + failure process was simulated and the Multicontinuum Theory (MCT) was + used to determine the stress states in all specimens considered. The + strain energy release rate (SERR) as a function of crack length was also + utilised to gain further understanding into the fatigue behaviour. + Overall the FE models are able to accurately predict the bonded, bolted + and hybrid joint strengths. SERR results suggest it is vital to place + fasteners closer to the ends of the overlap to suppress the peak peeling + stresses and to delay the effects of early crack initiation. This + overall improves the longevity of a conventional bonded joint design. + (C) 2016 Elsevier Ltd.
