PLASTIC AND ELASTIC PARAMETERS OF DISLOCATIONS. III.

Delocalization of plastic shear boundaries which transforms a discrete dislocation into a real one is discussed. Formulae are obtained for the elastic field of a dispersed plastic shear boundary - the second component of the elastic field of a dislocation, for an unbounded elastically isotropic medium. Expressions are found for the forces operating on a dislocation in the elastic field of the dislocation itself (spontaneous reaction), in the elastic field of another dislocation due to a point defect, in the field of self-vibrations of a specimen and in the elastic stress field due to loads on the surface of specimen.
