I am using TNM to simulate Celcon-M90 material, calibration shown good fit with experiemental data (Uniaxial tensile data). Results (ANSYS) shows huge stresses in the order of ~320MPa and equivalent plastic strain of '0', however the max/break point in the experimental data is at ~67MPa. Analysis has simple compression loading, however the critical region of interest is in tension that made me convince to use uniaxial tensile data (I don't have any other experimental data). When I rerun the analysis with elasto-plastic model, I could see max equivalent stress as ~77MPa. Is there something going wrong in the analysis? Can anyone help me to interpret the results?
Thanks in advance,
