Numerical study of the large strain behavior of extruded magnesium alloy AM30 tube by elastic viscoplastic self-consistent model

The anisotropic mechanical behaviors of the newly developed magnesium alloy AM30 are modeled by the elastic viscoplastic self-consistent (EVPSC) model. This is the first time to numerically study the mechanical behavior of AM30 based on EVPSC model. Three tests of uniaxial tension and compression along extrusion direction (ED) and ring hoop tension at temperature of 200 °C and strain rate of 0.1 s−1 are studied. It is found that extension...
