Non-Linear Viscoelatic Material in HM - Simulation

Hello everyone, 

 

i want to simulate a tensile testing with a non linear viscoelastic material (ABS). I have generate some stress-strain charts where i get the material values (E, ...).

So my questions:

 

• Which solver is for this case the right one? (Optistructe is for linear right? or maybe RADIOSS?)
• How can I define a non linear viscoelastic materialcard in HM? (Does it depends on the solver?)

 

The material and the geometry are non linear. This must be taken into account. 

 

I am grateful of every answer.
