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.
Â
I read the documentation in two parts:
PolyUMod-TNV
PolyUMod-Parallel-Network
Â
But so far I have not had satisfactory results from my attempts to use MCalibration & PolyUMod.
Â
Maybe someone already tried to solve this problem?
