## Abstract The following problem, of interest in the theory of workβhardening, is considered. Under the influence of an applied stress dislocation loops are emitted from a source and pile up against an elliptical barrier. To determine their equilibrium number and distribution.
The dependence of the hardening effect of precipitate particles is computed in terms of a model in which the precipitate particles cause the dislocations from activated Frank-Read sources to form closed loops about the particles. The back stress resulting from the closed loops increases the effectiv
