Interfacial Edge Dislocations and Dislocation Walls in Anisotropic Two-Phase Media.

摘要

Explicit expressions are obtained for the displacement and stress fields of an edge dislocation in the plane interface in a two-phase anisotropic medium. These expressions are used to calculate the stress field of an infinite vertical array of equally spaced interfacial edge dislocations. It is shown that in a two-phase medium, either anisotropic or isotropic, an edge-dislocation wall at or near the interface has a long-range stress field, in contrast to the result for a single-phase medium.
