On the elastic field around an edge dislocation with application to dislocation vibration

The elastic field around a long, straight edge dislocation moving with an arbitrary velocity is derived in the form of time integrals. An electromagnetic analogy, which is known to apply to a screw dislocation, is found to be absent. The results are applied to an edge dislocation oscillating with a small amplitude. A brief discussion of the scattering properties shows no significant difference between screw and edge dislocations.
