A cyclic small-strain plasticity model for wrought Mg alloys under multiaxial loading: Numerical implementation and validation

Basal-textured wrought magnesium alloys are inherently prone to mechanical twinning/de-twinning during cyclic deformation at room temperature. They, subsequently, exhibit distinctive flow curve attributes, which are impossible to describe using conventional plasticity models developed for symmetric/isotropic metals, deforming mainly by slip. A continuum plasticity model is herein proposed, in such way that accounts for various...
