Thanks Sebastian. To my opinion, you need to input more data points in the small strain region. Check how the stress jumps from ~427 MPa to ~827 MPa from zero to 0.02 strain. You need to add more intermediate values in this range otherwise Ansys Mechanical software will linearly interpolate your data. This may explain the discrepancy in validating your simulation against experimental data (in your first post) that shows up as a linear curve in the small strain regime.
