Abstract

The paper presents the results of numerical analysis of mesoscale deformation in three-dimensional polycrystals under tension. The three-dimensional models of polycrystalline structures are generated by a step-by-step packing method. Elastoplastic grain response is described taking into account the Hall-Petch relation, strain hardening and elastic anisotropy at the mesolevel. The nucleation and development of plastic shear strains on the surface and in the bulk of polycrystalline specimens are studied in a numerical experiment. The role of free surface and grain boundaries in the evolution of mesoscale deformation is analyzed.
