The internal stress relaxation modeling in the polygonization in alkali halide single crystals

Abstract

The evolution of the dislocation system during annealing in the absence of external loading after the three-point bending of a single crystal with a NaCl-type lattice, pricked out along the cleavage planes is modeled with the discrete dislocation dynamics method. The change of the average shear stresses value produced by the dislocation structure in the surrounding crystal and stresses acting on the dislocation ensemble themselves are obtained.
