An extended Taylor model to simulate localized deformation phenomena in magnesium alloys

In this paper, a constitutive framework based on a rate-dependent crystal plasticity theory is employed to simulate localized deformation phenomena in hexagonal closed-packed (HCP) metals such as magnesium. A new and simplified method to account for deformation twinning is proposed. The new framework allows the twinned zones and the parent matrix to rotate independently. This is an extension of an earlier model presented by Lévesque et al. …
