Polycrystal modeling of tensile twinning in a Mg alloy during cyclic loading

Introducing a volume transfer scheme to handle twinning, the elasto-viscoplastic Taylor–Lin model was employed for the first time to investigate the effect of tensile twinning on the low cyclic deformation behavior of a strong basal textured Mg alloy at room temperature. {101¯2} tensile twinning was predominately activated together with massive de-twinning. The numerical simulation reproduced the experimental cyclic stress–strain curve and twinning activity in good agreement with experiments obtained by orientation mapping and suggested Taylor deformation mode.
