How to add material nonlinearity for composite(orthotropic) materials in ANSYS?
Good morning to all,
I am a research scholar working on nonlinear (geometric and material nonlinearity) buckling analysis in composite materials (GFRP). However, I modeled everything in ANSYS but, I want to add material non-linearity in the model. For isotropic material, multilinear isotropic hardening is given in ANSYS to include material nonlinearity. But, which is the better option for composite material nonlinearity?
It will be great if someone clear my queries..
