Abstract
The stress and displacement fields of an edge dislocation that climbs with a uniform velocity are derived. This solution has application for the determination of the stress and displacement field arising from the anomalous edge component of a moving partial dislocation. The climb motion of the anomalous edge component does not involve diffusion of point defects and is not restricted to slow velocities. The self‐energy of a climbing edge dislocation also is determined. It is found that the self‐energy diverges as (1−V 2/c 2)−1/2, where V is the dislocationvelocity and c is the transverse sound velocity when the dislocationvelocity approaches the slow sound velocity. This divergence is not as strong as that of the gliding edge dislocation [which is (1−V 2/c 2)−3/2].This publication has 2 references indexed in Scilit:
