Numerical modelling of large strain deformation in magnesium alloy AM30

In this paper, a new constitutive framework based on a ratedependent crystal plasticity theory is presented to simulate large strain deformation phenomena in HCP metals such as magnesium. The new framework is incorporated into in-house codes. The simulations are performed using a crystal plasticity model in which crystallographic slip and deformation twinning are the principal deformation mechanisms. Simulations of various stress states …
