Abstract
It is shown that the displacement fields and the stress fields associated with various dislocation arrangements in an isotropic elastic solid can be easily obtained by integrating the displacements found for various kinds of point nuclei of strain. Examples are given. It is found that a platelike precipitate of centers of dilatation is not completely equivalent to an edge dislocation loop. One must include, in addition, forces acting in the plane of the loop at the edge of the loop. The implications concerning the elastic force acting on point defects near a precipitate are discussed.This publication has 5 references indexed in Scilit:
