A theoretical model to describe the nanovoid growth by emission dislocation shear loop in nanocrystalline metal under equal biaxial remote stress was developed. The critical stress for emission of dislocation was derived by considering the effects of surface stress. Within our description, dislocations emitted from surface of nanovoid were piled up at grain boundaries and the stress field generated by arrested dislocations can prevent further dislocation emission. The effect of grain boundary of nanocrystalline materials on nanovoid growth was investigated, and the results showed that the smaller of the grain size, the harder for the nanovoid growth.
