We investigate the nonuniform motion of straight dislocations in infinite media using the theory of incompatible elastodynamics. The equations of motion are derived for nonuniformly moving screw dislocation, gliding edge and climbing edge dislocations. The exact closed-form solutions of the elastic fields are calculated. The fields of the elastic velocity and elastic distortion surrounding the arbitrarily moving dislocations are given explicitely in the form of integral representations free of non-integrable singularities. The elastic fields describe the response in the form of nonuniformly moving elastic waves caused by the dislocation motion.
