摘要

With a small strain assumption, a multiscale model of damage initiation in Low-Cycle Fatigue (LCF) is proposed to describe the cyclic damaged behavior of polycrystal under different cyclic loading paths (simples and complexes). The evolution of the internal variables on the Crystallographic Slip System (CSS) are recorded under these loading paths up to final fracture of the Representative Volume Element (RVE). It is well recognized that the model can appropriately reproduce the macroscopic damaged responses of polycrystals in plastic fatigue.
