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.

Can I retrive strain increment in ABAQUS with python?

Dear all,
I just finished extrusion process simulation in ABAQUS with the input of stress-strain data. Now I want to retrive the strain increment of certain element during each deformation increment. Surely one can write straininc to a *.txt file when simulating with VUMAT. But the simulation of extrusion will be extremely slow with VUMAT. So How can I get the strain increment when simulating with the input of stress-strain data?
Best regards,
