Before revision: Comparatively, for simple cubic lattices, b = and hence the magnitude is represented by Generally, the Burges vector of a dislocation is defined by performing a line integral over the distortion field around the dislocation line where the integration path is a Burgers circuit around the dislocation line, is the displacement field, and is the distortion field.
