Dynamic Edge Dislocation Displacements and Peierls Strains in a Linear Elastic Strip.

摘要

A Fourier transform image method is used to obtain the displacement field of an edge dislocation in a finite-width strip. Static,subsonic,transonic,and supersonic solutions are presented. Using the static solution,the Peierls strain is calculated,as a function of the length and the width of the strip. (ERA citation 04:047159)
