I have to study a transversely isotropic material (composite) . It has a very different young's modulus in compression (0.6 GPa) and tension (4.7 GPa) in the transverse direction to fiber (along the fiber direction the young's modulus are the same).
There is a way to study this situation?

There is a material called Cast Iron that can provide a different young's modulus in Tension and Compression.
Here is another discussion for a student that had fibers in concrete and used a more manual method.

Thank you for your answer.
I have already seen Cast Iron, but it's only for isotropic material, isn't it?
Maybe my question wasn't so clearly, but when I wrote "(along the fiber direction the young's modulus are the same)" I mean that in compression and in tension in this direction are equals, but the value is different from transverse direction.
So I have a transversely isotropic material. I think Cast iron isn't the solution or is it possible to use it for my case?

ANSYS provides a sophisticated Composite modeling environment. There is a component called ACP (Pre) for defining the layers of fibers and the matrix that supports them. That model feeds into a Static Structural analysis system where the stress and strain are solved, then the solution is fed into another component called ACP (Post) where stresses in each layer can be investigated. There are many YouTube videos on the ANSYS ACP models that you can watch. Just go to YouTube and search on these three words: ANSYS ACP tutorial
