Hello,
Thanks for your answer. I guess that one of the issue is to, firstly, make the pre-stress, using some hyperelastic material (Mooney-Rivlin), and secondly calculate the frequency response using a viscoelastic material (Boltzmann's relaxation model). But what is the procedure to model a material in 2 steps (stationary and then frequency) and have a different material model for each step?
Regards
HI,
You should set up a Prestressed Analysis – Frequency Domain . That probably requires the Structural Mechanics Module. One challenge in this type of problems is to select a material model that has a dynamic stiffness (storage and loss moduli) that closely represents that of your rubber material.
