Abstract

The effects of through-thickness texture gradients on instabilities and localized deformation in FCC polycrystals are investigated. In-house finite element analyses based on a rate-dependent crystal plasticity model have been developed to simulate large strain behaviour for sheet specimens subjected to plane strain tension. Modelling of the polycrystalline aggregates is carried out at various scales, and predictions of localized deformation are compared against each other.
