Dear All, I request some light on modeling nonlinear transversely orthotropic material in Mechanical APDL (Classical ANSYS). We have successfully validated cases (Concrete columns wrapped with FRP confining material) using linear-elastic orthotropic behavior for outer wraps modeled with SHELL 181 elements. Is here any way to model plasticity (non-linear stress strain curves) for transversely orthotropic material ? Any reference or direction of search would be greatly helpful.

The Generalized Hill plasticity model would be worth reviewing. John Deibler Pacific Northwest National Lab "All models are wrong.
