Thank you for the reply, your explanation is very helpful to me.

(i) I don't use Isotropic Elasticity to define Young's Modulus(E), Poisson's Ratio(v), Bulk Modulus and Shear Modulus, specifically G, but still find G-inf [Fig.1]. Have you tried yet?

(ii) The line in Curve-fit [Fig.2] is different from the line in Prony Shear Relaxation (almost straight line) [Fig.3]. Is that a problem?




Thanks for your help, thanks for your time.
