Introduction to mcalibration "Stress relaxation Check"
Hello, I performed the introduction to mcalibration calibrating a TN model following the instructions from the link.
I saw the prediction for stress relaxation and wanted to check it performing an Ansys simulation, I didnt get the Stress relaxation response of the material in the simulation. Maybe I made a mistake, so I tried replacing the TN material data for an hiperelastic + prony series to check the stress relaxation of the element, getting the desired response for H+P but not for TN model.
i tried performing the TN model with t = 60 and t = 120 simulations but saw 0 relaxation response.
Your image seems to indicate stress relaxation. Can you explain more about the problem?
