Effect of screening of the elastic field of the disclination located at the interface of two half-spaces by a dislocation ensemble

Abstract

The self-consisted dynamics of a dislocation ensemble in the elastic field of the disclination located at the interface of two half-spaces has been considered for two cases, namely, for half-spaces with different densities of mobile dislocations and for a bicrystal where dislocations are absent in one half-space. The elastic energy W of the disclination screened by the dislocation ensemble has been calculated for the rectangular zone centered relative to the disclination. It has been shown that W increases as ∼ \(\sqrt R \) (R is the transverse size of the zone in the plastically deformed half-space).
