How to determine the parameters of pinching4 material
I am a beginner, now I have some difficulties in determining the parameters of pinching4 material (rDisp, rForce, uForce, K1, K2, K3, K4, Klim...). , I checked a lot of papers, but the above only said the fitting calculation, did not say how to calculate, can anyone give me some help, thank you very much.
