Hello

Can XFEM-Based Crack-Growth Simulation be used on elastoplastic or nonlinear materials?

I already tried SMART, and I know it's not possible with that.

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: 

3.1. Understanding Crack-Initiation and -Growth Mechanics --> 3.1.3.6. Crack-Closure Functions

Thanks for the response

I'm trying to simulate static crack growth of elastoplastic materials, so I don't think crack-closure functions can help. Is there any other way to do this?
