Plasticity in XFEM

Hello, Uno,

There should be no difficulty for plasticity with eX-FEM once you have implemented linear elastic case,

because in practice the only differences between eX-FEM and standard FEM are just shape functions and their corresponding integration technique.

Any bulk constitutive law used in standard FEM can be used in eX-FEM.

Hello,

As far as I understand from the previous blogs: we can now embed XFEM in ABAQUS. Is this approach restricted to linear elastic behavior? Can we simulate fracture propagation in an elasto-plastic material ("XFEM coupled with ABAQUS" type analysis) or is this approach only limited to fracture propagation in elastic materials.

Thanks,

Uno.
