Model of accommodation of planar shear mesodefect

Abstract

A model of accommodative plastic deformation and relaxation of elastic energy of planar shear mesodefects at grain boundaries resulting from inhomogeneous plastic deformation of polycrystals is proposed. It is shown that this process can be carried out by sequential splitting off from the mesodefect and leaving dislocation walls into the grain body.
