Good afternoon,

I need to simulate the process of cyclic compression of soft polyurethane foam, taking into account the viscous properties.

Below are two graphs of compression and unloading  - one cycle each, having different constant strain rates.

 

I read the documentation in two parts:
PolyUMod-TNV
PolyUMod-Parallel-Network
 
But so far I have not had satisfactory results from my attempts to use MCalibration & PolyUMod.
 

Maybe someone already tried to solve this problem?
