摘要：

A disclination dipole wall model of grain boundaries incorporating a dislocation emission mechanism has been developed. Uniform and non-uniform disclination spacings have been treated, and the complete stress field equations have been solved for the uniform case. Two models of dislocation emission from the disclination dipoles are considered as plastic deformation mechanisms. A stable grain boundary with limited plastic deformation potential is described.
