摘要：
During plastic forming of magnesium alloy parts, multiaxial deformation state with shear and normal strain components is frequently observed. Therefore, torsional, torsion-tension coupling, and torsion-compression coupling behaviors of AZ31 magnesium alloy extruded bars are numerically investigated. The elastic visco-plastic self-consistent model with the twinning and detwinning scheme, in conjunction with a torsion specific finite element method, is employed. Stress-strain response, twin volume fraction, relative activities of deformation mechanisms, and deformation textures are obtained and used to interpret the multiaxial deformation behaviors of Mg alloys.
