Abstract
We have analyzed the equilibrium configuration of a pile-up of edge dislocations in the total field of external and internal elastic stresses produced by a wedge junction disclination. The conditions for the loss of pile-up stability and the passage of a plastic shear through the force barrier generated by the disclination have been analyzed.
