Hi All,

Does someone have experience in modeling PU?

So far, I have found one paper that introduces a const. model

for PU ([I]H.J. Qi and M.C. Boyce, Stress-strain behavior of thermoplastic

polyurethanes, Mechanics of Materials, Volume 37, Issue 8, Pages 817-839, 2005[/I]).

I was wondering if someone knows of any other models that have been developed for PU?

Thanks,

burgeand

I am very familiar with the Qi-Boyce model.

An alternative model, which I have developed, is the Parallel Network Model ([URL= https://polymerfem.com/index.php?pageid=umats]PNM[/URL]). This model is very cool and typically superior to the Qi-Boyce model in terms of accuracy.
