[Solved] Temperature dependent relaxation in tension and compression with TNM

Hello Dr.Jorgen,

I was wondering if the three network model in polyumod can capture the stress relaxation experimental data of HDPE in both tension and compression at temperatures (20,30,40,50,60,70,80 C). So far it was able to capture the relaxation behavior in compression with good accuracy, However, I just want to be sure that it can capture the relaxation behavior in tension before I go ahead with experimental testing.

Good question. Yes, the Three Network (TN) model works for both tension and compression. I just found some old HDPE data that I have, but unfortunately is is only tension data.
