Abstract

We have proposed Analytical Iterative Uniaxial Stress Correction Method that corrects the average stress in this multiaxial state to the stress value in the uniaxial stress state by using iterative numerical simulations, and for some iron-based metals and aluminum alloys, the true stress - true strain curve in the entire strain range is obtained. In this paper, the validity of this stress correction method was verified using the design optimization / probability / statistical analysis tool LS-OPT.
