Screw dislocation near interface in gradient elasticity
The gradient elasticity theory was used to consider a straight screw dislocation near a flat interface separating two elastic media with different elastic constants and gradient coefficient. Solutions for the dislocation stress fields and for the 'image' force that acts upon the dislocation due to the interface were derived. The dislocation behavior near the interface was characterized.
