Hi,

Ready models for material plasticity are still missing, so the only way to make such simulation would be via writing a user-defined UMAT subroutine. The current status is described in the discussion

Hi,

Even though this is an old topic, it is very interesting for me.
I would like to perform some structural analysis on 2d geometries (e.g. hollow disk) with nonlinear material law (stress-strain curve).
Do you know if it is possible to run such an analysis with Elmer?
If yes, could you suggest to me some good references to study?

Thanks
