XFEM
Submitted by Uno Mutlu on Wed, 2008-04-09 15:37.
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.

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.
