We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hello,

XFEM only supports usage of linear elastic materials. In terms of plasticity effects during crack growth, you may want to consider whether a crack-closure function fits your application. For this, in the MAPDL Fracture Analysis Guide, see the following section:
