Modeling cyclic plasticity of additively manufactured alloy Mar-M-509 using a high-performance spectral-based micromechanical model

A high-performance full-field spectral crystal plasticity model referred to as MPI-ACC-EVPCUFFT is adapted to study the deformation behavior of additively manufactured Mar-M-509® cobalt-based superalloy. The model features a dislocation density-based hardening law for the evolution of slip resistanc...
