Finite element modelling and diffraction measurement of elastic strains during tensile deformation of HCP polycrystals

Abstract:: In this paper a 3D, elastically anisotropic crystal-plasticity based constitutive model is used to describe cyclic deformation and hardening of polycrystalline HCP (hexagonal close-packed) materials. A diffraction post-processor is developed to allow critical assessment of model predictions against XRD data. Model results for titanium alloy Ti-6Al-4V are compared with synchrotron high energy X-ray polycrystalline diffraction data. The significance of elastic anisotropy and three-dimensionality of the model is discussed.
