The `CrackFrontNonlocalStress` is useful for extending cracks that are approaching free surfaces because the interaction integrals computing `KI` and `KII` are affected when the integration domain intersects the free surface. `CrackFrontNonlocalStress` computes an average of the stress over a box-shaped domain at each crack tip point that is centered on the crack tip and extends [!param](/VectorPostprocessors/CrackFrontNonlocalStress/box_length) in front of the crack tip. The [!param](/VectorPostprocessors/CrackFrontNonlocalStress/box_height) is the dimension normal to the crack face, and [!param](/VectorPostprocessors/CrackFrontNonlocalStress/box_width) is the dimension tangential to the crack face. [!param](/VectorPostprocessors/CrackFrontNonlocalStress/box_width) is not used in 2D problems. Unlike the other stress integrals, like the [InteractionIntegral.md], that use the [CrackFrontDefinition.md], `CrackFrontNonlocalStress` is not set-up by the [/DomainIntegralAction.md]. -In the following input file example, the mesh consists of a 3D plate with a hole in the middle.
