As you may know, Young's modulus of a CFRP material which is subjected to tension, is different than in the case of compression. See the reference [1], [2] and [3]. For example, the material "AS4 12k/938" has Young's moduli of 154 GPa in tension, 125 GPa in compression [1].

As far as i know, Cast iron model does not allow to have different Young's modulus tension and compression. Under these circumstances, how we define a material such that through ANSYS Workbench?

Hi, I think you should script it with Ansys APDL maybe, and you may find some tips and answers in previous posts on the forum:
