Integration algorithm for a modified YoshidaUemori model to simulate cyclic plasticity in extremely large plastic strain ranges up to fracture
A model to describe cyclic plasticity till fracture was implemented. An adaptive substepping algorithm was proposed for the backward-Euler method. The algorithm can ensure convergence at extremely large plastic strain ranges. A method to determine the optimal substep length was proposed. The plasticity model can well simulate cyclic plasticity of mild steel till fracture.
