hi
what is the reason in elastic-plastic material like MAT36 we should use the effective stress-strain curve
thanks

Law 36 in Radioss is the non linear material ,and the functions are for the work-hardening portion of the stress-strain curve (for example, plastic strain vs. stress) for different strain rates
