    Abstract

    A microstructure-based model for polycrystalline titanium is constructed and implemented in finite-element calculations of uniaxial tension. The grain structure is considered explicitly, with grain orientations being given by a set of local coordinate systems related to the crystal lattice. Elastic-plastic anisotropy on the grain scale is described using generalized Hooke's law and the crystal plasticity theory. It has been found that the plastic deformation of grains is accompanied by crystal lattice rotations within and near localized shear bands and along grain boundaries. A correlation between plastic strains and Schmid factors of grains is discussed.
