ParisLaw
Description
The ParisLaw Reporter computes the crack extension size at all active crack front points in a fatigue crack growth scenario. Crack front points are provided by the CrackMeshCut3DUserObject UserObject and fracture integral values are provided by the Interaction Integral vector postprocessor, which can be set up by the DomainIntegralAction. The code is based on the Paris law and requires Paris law parameters "paris_law_c" and "paris_law_m" as the input. The amounts of crack extension at the crack front nodes are scaled such that the point with the largest effective K will have an extension equal to "max_growth_increment".
