Furthermore, in combination with homogenization theory, plastic material parameters are predicted by using yield loci fitting on the macroscopic limit stress domain. The proposed approach is validated through

A?common feature of these methods is to estimate directly these cyclic states, profiting, thus, big savings in computer time. The elastic shakedown is the most important, in terms of structural safety, cyclic state. Most of the exi
