LMS Samcef Fracture Mechanics

Model structural integrity, including crack propagation, using XFEM

LMS Samtech Samcef Fracture Mechanics has standard modeling capabilities that are dedicated to the propagation of cracks in materials, or fracture mechanics. The fracture mechanics solution includes specific elements that allow you to capture the stress field singularity, as well as some that are dedicated postprocessing so that you can compute stress intensity factors, the components of Rice’s J-integral and the energy release rates by mode.

An extended finite element method (XFEM) provides 3D modeling of crack propagation (independently of the mesh). You can model several cracks with automatic fatigue crack propagation (Paris, Elber, Forman, Nasgro) with automatic remeshing during propagation. With this XFEM approach, the definition of the crack is easier because the model doesn’t require a change to the geometry or mesh with the accuracy of the solution.
