Popis:	The plastic flow process around a spherical dilatated inclusion has been previously sketched as a “dislocation shell” emission idealizing patterns of collectively moving prismatic circular loops. This elastic description of relaxation is here reintroduced from the discretization of the continuous plastic solution into elementary plastic deformation fields taken compatible except in a thin leading shell-like zone. The assumptions which yield to the elastic problem of the current equilibrium for n -imbricated hollow spheres with overlapping radii are specified and the provided flow and internal stress fields are compared to those from the continuous plasticity modeling on the one hand, and from a dislocation loop pattern on the other hand.
