How to define an anisotropic material with asymmetric elastic compliance/stiffness matrix in ANSYS APDL?

I need to model an anisotropic material in which the Poisson's ratio ν_12 ≠ ν_21 and so on. Therefore, the elastic compliance matrix wouldn't be a symmetric one. In ANSYS APDL, for TB,ANEL...

Thank you all.Can you suggest me how to use negative slope of stress strain curve in ansys ?

Ahmed Mirghani

You have to use true stress vs plastic strain (Always +ve values of slope) as an input in ansys. Ansys doesn't accept -ve slope values "After necking occures".
