I am trying to simulate a neo Hooke model in abaqus but I have only lame's constants to define potential function mu and lambda. I am confused with abaqus terminologies, it needs C10 and D1.

After some search I found that lame constant lambda is shear modulus mu and C10 = mu/2

And lame constant mu = bulk modulus kappa, D1 = 2/kappa

I am bit confused with these terminologies as haven't done such analysis before. Can someone comment?
