How are Compression Modulus and Tensile Modulus related to Lame` constants?

Hello everyone

I have a material with a compression modulus and tensile modulus along with Poisson's ratio. Are compression modulus and tensile modulus related to the Lame` constants? Or does this material fall under 'cubic symmetry' which needs three elastic constants? In that case, how are they related to the elastic coefficients (C12, C44 or C11)?

I need to incorporate these material properties in ABAQUS. How do I model this material in ABAQUS?

Any lead on this problem is appreciated. Thanks a lot.
