Hi Guys,

I have the shear relaxation modulus given as: G(t)=Go*EXP(-t/tau). In ABAQUS, the normalized shear modulus for one term in Prony series is given as: g(t)=Go(1-g1(1-EXP(-t/tau)). The parameters that must be entered in ABAQUS are g1 and tau. For Maxwell (in our case) G(t=infinity)=0.

Consequently, g1=1-G(t=infinity)/Go=1. ABAQUS requires that g1 must be less than 1. Has anyone encountered this problem?

thanks

Ah
