Viscoelastic materials

mdsimulationgroup

Hello,

I'm interested in modeling a viscoelastic materials between to hard materials under compression.

Are there recommended material type for something expected to deform greatly?

I see the Neo-Hooke and Mooney-Rivlin materials but wasn't sure if there were others that might be better?

Or is this something Mecway might not be designed to deal with?

Thanks,
Frank

CCX has viscoplasticity but it's not in the Mecway GUI. You can probably use it by writing some cards by hand. See *VISCO and *CREEP in the CCX manual.

CCX also has other non-viscous material models. See *HYPERELASTIC and *HYPERFOAM.
