Bonjour!

I have an orthotropic material with only one young modulus out of three that exhibits a nonlinear behaviour, i managed to propose a model for it ( based on an exponential function) and my question would be:

Is there a way to add such material to sw library for nonlinear analysis???

All help is highly ( i mean like up up up) appreciated

Thanx

Laila

so you want 2 directions to be linear and one to be nonlinear (vonmises?) with a stress strain curve?

what have you tried so far?
