Hello Dr Bergstrom,
I need to model an orthotropic elastic material and I am intending to use the Tsai-Wu (3D) stress failure behavior available in the polymod libraries (I have incorporated this failure model through the paralel network model -PNM)
Although the orthotropic failure behavior works fine, in the TNM model I cant model the orthotropic elastic pre-failure behavior.
Is there any way to incorporate orthotropic elastic together with Tsai-Wu 3D stress failure?
Thanks a lot.
