Crystal Plasticity Based Numerical Modelling of Large Strain Deformation inHexagonal Closed Packed Metals

In this chapter the finite strain plastic deformation of hexagonal closed packed polycrystals have been simulated using crystal plasticity theories. The simulations have been carried out using a rate-dependent elastic-viscoplastic crystal plasticity constitutive models. Two models are considered in the analyses; a model based on the classical Taylor assumptions and a model based on crystal plasticity finite element method. The plastic …
