Hi,

I want to use Abaqus to model a viscoelastic material. I am working in frequency domain and have real and imaginary part of Shear and Bulk modulus (Gs,Gl,Ks,Kl as in manuals). But the program asks about real and imaginary part of nondimensional parameter,g. As explained in the manual g has a relation with G but it need G(infinity) and also frequency.
Now, I don't know how to go from G to g and define my model. Also there is no place in program for G(infinity), so i am totally confused how this works.

I appreciate your help,
Thanks
Majid

In short, you need to know either the shear modulus in the limit as the frequency goes to 0 or goes to infinity. You can then determine the dimensionless variable g.
