Analysis of deformation-induced twinning at finite strains based on energy minimization
AbstractIn the present contribution, an energy-based description of phase transformation suitable for the modeling of crystal reorientation during twinning is proposed. A homogenized relaxed stored energy (volume averaging) is utilized for the
simulation of the pre- and post-twinning hardening form of magnesium single crystal. The proposed energy-driven model is
applied to analyze the activity of deformation systems inside the twinning related phases. It is shown that the activity of the inter-twin dislocation systems accommodates the plastic strain at larger deformation.
