Hello,

I am building a material model for a nonlinear viscoelastic polymer in ABAQUS. For the beginning I just want to simulate an uniaxial tensile test. But now I want to know which damage criteria do I have to use? Which parameters do I need to simulate a real necking of the sample until damage. (dynamic explicit)

I already have the density, the E modulus, poisson's ratio, prony terms (viscoelastic).

Thank you!
