The elastic modulus for the tension and compression is different as you can see from the experimental data. I tried to correct the code, but the problem still persists. Here is the corrected code. I inserted an additional data point for zero strain and yield stress. However, the second data for tension and compression already has the yield stress values. Therefore, I am a bit confused about what to do. Do you have some other recommendations? I am also including the link to the paper where I got the input parameters for the FEM.
