Hello all,
I am trying to use a model (3D solids) with a 3D orthotropic material and nonlinear material properties (plasticity). I am simply defining the material as bi-linearly plastic, but it seem as if NEi Nastran does not recognize the plasticity introduced and considers the material elastic. I have tried running the model using a linear orthotropic material, as well as with a nonlinear isotropic material, both of which have behaved just fine.
Does anyone have any idea as to what might cause this?
Regards,
Niklas
