000014317 520__ $$2eng$$aExperimental tests under different proportional loading conditions were performed to investigate the constitutive behaviour of a rareearth magnesium alloy (ZEK100) rolled sheet at room temperature, under quasi-static conditions. An anisotropic yield function for HCP materials with yield asymmetry, CPB06, was calibrated from monotonic experimental data. To evaluate the performance of the yield criterion, nonproportional experiments were performed with an emphasis on the cyclic shear test. It was observed that although slip and twinning mechanisms govern the response of the magnesium alloy under proportional loadings, reversed loadings can activate the de-twinning mechanism as well leading to a substantial Bauschinger effect.
