I have tensile test result of a material at different temperatures - elongation vs stress. From these results, how can I calculate effective plastic strain for flow curves?
The yield point with zero plastic strain and the different yield stresses for different temperatures should be the starting point of the flow curves.
As an example based on the given values: flow curve 25 deg C: 950 MPa, 0.0 plastic strain, 1000 MPa, 0.04 plastic strain. flow curve 100 deg C: 700 MPa, 0.0 plastic strain, 800 MPa, 0.03 plastic strain. The yield point values are pure guesses on my part, but should demonstrate the idea.
I understand the stress input is called flow stress in the GUI, but the yield point has to be considered as the starting point of the flow curve.
