Hello
I have been searching for parameters for known type of steel for use in a non-linear analysis to make approximisations in the plastic area. As far as I have understood, the curve in the plastic area is defines as follows: ?=(1-?)Y+?E? , where ? is the strain hardening factor, Y is yield stress. How is this factor (?) compared to isotropic / kinematic hardening factor? Can you choose ? to be a function if the hardening factor is linear, exponential, logarithmical etc., or does another function apply to this?
Regards
Tommy
