Descrição: The effect of a textured surface layer on the deformation behavior of surface-modified titanium is numerically investigated. A three-dimensional polycrystalline model accounting for the grain morphology was generated by a step-by-step packing method. A crystal plasticity-based constitutive model describing the anisotropic elastic-plastic behavior of individual grains is implemented in a dynamic boundary-value problem that is numerically solved using ABAQUS/Explicit finite element package. Two sets of calculations for polycrystalline models with textured and untextured surface layers were performed. Conclusions on the surface texture effect on the stress and strain fields and surface roughening in the surface and in the bulk of the polycrystals were drawn.
