Hello!

I'm trying to model theee behavior of a car door weather seal which is composed of compressive foam and incompressible elastomer.

In static, the behavior is as I were expected to. Unfortunately, in dynamic, I have also the Prony serie to describe the compact's viscoelasticity.

Do I need the same coefficients for the foam?
I know that one firm in France overlooks the viscoelasticity for foams...

What do you think?
