Does http://books.google.com/books?id=wh...ge&q="frank read source" dislocation&f=false" help answer your questions? The center of the pinned dislocation (later to become a dislocation loop) moves in the direction of the shear stress. The Burgers vector points in the direction of the shear stress also (for the entire dislocation).
