✦ Synopsis

Various equilibrium dislocation distributions in finite and infinite media were recently analyzed [51 both from theoretical and computational standpoints. In this paper we shed further light on this issue, by elaborating on a variational procedure that gives the required equilibrium conditions: the glide forces on each dislocation represent a set of self-equilibrating forces. The derivation is carried out in a general 3-dimensional setting, with adequate specifications for edge dislocations in plain-strain case.
