How to add viscosity into a hyperelastic material such as Mooney-Rivlin rubber in LS-DYNA?

25 July 2024 0 6K Report

Hi,

I am working on a head FE model and want to try different material types on brain. I read some papers that use Mooney-Rivlin rubber model and wondering if i can add viscosity into it. Is it possible in LS-DYNA? Thanks to any reply.
