Virfac Crack Propagation Lifetime

Virfac® Crack is a software product for the computation of the stress intensity factors along the front of three-dimensional cracks and the prediction of crack propagation under fatigue loading. This module implements the eXtended Finite Element Method (XFEM) for the modelling of cracks in a mesh-independent fashion. The stress intensity factors are computed accurately thanks to dedicated enrichment functions which improve the quality of the solution at the crack front. Moreover, Virfac® Crack offers unique algorithms for modeling the propagation of multiple, 3D cracks with no limitation on the crack shape.
