How to determine G12 if I have E1, E2 and v12?

[Fea_pather]

I intend to work with Composites in my simulations. I have a rough idea of the E1, E2 and the v12 properties I wish to use. With this, is it possible to predict the G12 (in-plane shear modulus) that should be defined in the FEA simulation to ABAQUS? Is there a method similar to the isotropic scenario, like G = E / 2 (1+v)???

Note: I intend to use a Plane stress formulation with Lamina material properties.

SolidWorks uses G_xy = (E_x*E_y)/(E_x+E_y+2*E_y*v_xy) if you don’t specify the shear modulus.
