Magnesium is among the lightest structural metals with a high strength-to-weight ratio. A widespread adoption of magnesium alloys in the industry, however, is impeded by its unorthodox mechanical behavior. The vast differences between activation energies of the slip systems in HCP magnesium, combined with profuse (and abrupt) activity of tensile twinning leads to an extreme plastic anisotropy. On top, there is intense strain heterogeneity, primarily, linked to the spatial coordination of twinning that also shows a strong dependence on crystallographic texture. The recent experimental efforts target a better understanding of magnesium (and validate polycrystal simulations) largely by investigating its mechanical response. In contrast, this work aims to incorporate temperature measurements of the dissipative response of Magnesium during deformation as well as the usual stress-strain measurements to infer a thermomechanical description of its plastic deformation. To this end, the temperature of a textured magnesium AZ31 sample is recorded under an IR camera. Then, stress and temperature obtained as a function of strain are compared with the output of a coupled thermomechanical Taylor-type crystal plasticity model, posed in the variational framework. - Advance of Collaborative Twinning Fields in Magnesium AZ31 via the Strain and Residual Intensity Channels in Microscopic Image Correlation
