nnYes I may have to do the multilinear hardening model because I don't want the material to exhibit perfect plasticity after the yield stress and ultimate strength because the bar in experiment would fail. nI have the tensile data for the rebar, how can I input the data to the model? nThe above is a screenshot for when it roughly reaches the yield stress. How can I calculate the values to input to the multilinear model?Thanks! n
