Numerical simulation of meso-mechanical response for superalloy ZSGH4169
Abstract
Based on crystal plasticity constitutive theory,polycrystalline representative volume element(RVE)was used to investigate the cyclic stress/strain response of superalloy ZSGH4169 in meso scale under multiaxial stress state at 650℃.The simulations reveal that ratcheting is significant under biaxial load control,which is consistent with uniaxial stress state commonly conducted in low cycle fatigue tests.The comparison of the two stress states...
