In this paper, the displacements and distortions produced by dislocation loops are represented as Fourier integrals, which are then reduced to obtain solutions for the fields produced by infinite straight dislocations, a finite straight segment of a dislocation line and an elliptical dislocation loop.
Abstract
Representations of the displacements and distortions produced by dislocation loops are given as Fourier integrals. These integrals are then reduced, to obtain solutions which are more explicit than any obtained previously, for the fields produced by infinite straight dislocations, a finite straight segment of a dislocation line and an elliptical dislocation loop, all in generally anisotropic media. The results should reduce the solution of many dislocation problems in which anisotropy cannot reasonably be ignored to fairly simple problems of routine computation.

The precise evaluation of derivatives of the anisotropic elastic Green's functions

TL;DR: Using Fourier transforms, a simple scheme for numerically obtaining derivatives of the tensor Green's functions of elasticity with great precision is derived as mentioned in this paper, which circumvents the need for solving an auxiliary eigenvalue problem and a related sextic algebraic equation.

The fracture mechanics of slit-like cracks in anisotropic elastic media

TL;DR: In this paper, the authors considered the problem of a slit-like crack in an arbitrarily-anisotropic linear elastic medium stressed uniformly at infinity, where the crack faces may be either freely sliding or loaded by arbitrary equal and opposite tractions.

Dislocations and Cracks in Anisotropic Elasticity

TL;DR: In this paper, the authors considered the elastic equations for the case in which the state of the solid is independent of one of the three Cartesian coordinates, and the stresses due to a dislocation, a wall of parallel dislocations, and a crack in an arbitrary non-uniform stress field were obtained.

Anisotropic elasticity with applications to dislocation theory

TL;DR: In this article, a general solution of the elastic equations for an arbitrary homogeneous anisotropic solid is found for the case where the elastic state is independent of one (say x3) of the three Cartesian coordinates x1, x2, x3.
