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...
I'm using a foam model with the strain energy function implemented in MARC. I've all the coefficients I need ( that is to say alpha_i , béta_i and mu_i).
I know that I can get the total volume ratio J, but I don't know how!!!
Does someone have an idea?

Hello,
I'm working with the behavior law of Ogden. I have the terms (from tests...) which define the compressiblity of the material (ie béta_i). Unfortunately the code I'm using needs the Poisson's ratio. How can I define the Poisson's ratio with the béta_i of the law?
I know that there is a...
