A temperature sensitive viscoplastic self-consistent (VPSC) model is developed to investigate the temperature and texture effects on the deformation mechanisms of a hot-rolled magnesium (Mg) alloy AZ31. A novel approach to incorporate the drag stress and dislocation-dislocation interactions as temperature dependent parameters is conducted in this paper. In addition; the model is coupled with a composite grain twin model; and dislocation density based hardening laws to predict the activation of the deformation modes participating in strain accommodation in Mg alloys: 〈a〉 basal slip; 〈a〉 prismatic slip; and 〈c+a〉 pyramidal slip; {101¯2} tensile twinning; and {101¯1} compressive twinning. The model is validated against an experimental study; realised on a hot-rolled AZ31 Mg alloy deformed at temperatures ranging from 25°C to 200°C under uniaxial tensile loads parallel to; perpendicular to; and 45° offset from the rolling direction of the material. The results of the simulations are in agreement with the experimental data in terms of hardening behaviour; deformation activities; and texture evolution. The presence of dynamic recrystallisation; which is observed experimentally at higher temperatures; shows the limitations of the present model. © 2020;
