| Abstract | A theoretical model has been developed to investigate the effect of a special cooperative process between two main modes of stress-driven nano-grain growth, i.e., nano-grain rotation and shearcoupled migration of grain boundaries, on the emission of lattice dislocations from a semi-infinite crack in nanocrystalline materials. The results obtained show that the above-mentioned collaborative process is highly conducive to the process of dislocation emission, thus, rendering strong crack blunting in nanocrystalline materials.
