Fig. 2: Stress distribution on repulsively interacting dislocations.
From: Repulsion leads to coupled dislocation motion and extended work hardening in bcc metals
a Resolved shear stress from externally applied stress on dislocation I and II (dashed line) and shear stress due to mutual dislocation interaction (line) at the closest point of interaction (nearest distance); b resolved shear stress due to the repulsive dislocation interaction along dislocation I and II. Dislocations are at distance dcrit. The relative positions are given in multiples of the lattice constant a0 and measured from the closest point of interaction.
