摘要: The recently developed large strain elastic visco-plastic self-consistent (EVPSC) model, which incorporates both slip and twinning deformation mechanisms, is used to study the lattice evolution in extruded magnesium alloy AZ31 under uniaxial tension compression. results are compared against in-situ neutron diffraction measurements done on same alloy. For first time, effects of stress relaxation creep respectively displacement controlled load tests numerically assessed. It found that has a significant effect measurements. also observed although does not significantly affect trend evolution, better agreement with experiments if included simulations.
