Orthotropic constants

(OP)
Hi All,

I modelling a composite material for which I have all the constants in the x and y direction, the problem is 2D.
The fact is ANSYS requires all the constants, and I am not sure whether I should use arbitrary values just to respect energy conditions or what.

Many thanks for any help

All the best

Favollo
