An efficient and robust approach to determine material parameters of crystal plasticity constitutive laws from macro-scale stress–strain curves

A severe obstacle for the routine use of crystal plasticity models is the effort associated with determining their constitutive parameters. Obtaining these parameters usually requires time-consuming micromechanical tests that allow probing of individual grains. In this study, a novel, computationall...
