Finite dislocation loop in anisotropic two phase medium

摘要

A scheme for calculating the stress field of a finite dislocation loop in multiphase medium is pro- posed. Taking the γ/α-Fe two phase medium as an example, adopting appropriate boundary condition, the "∞ field", "image field", resultant stress field produced by the finite dislocation loop, as well as the "image force" exerting on the loop, are calculated.
