摘要

摘要Yoffe（[The angular disocation.Fil.Mag.5（50）（1960），pp.161–175]）使用各向同性弹性确定的角位错的弹性场是一种方便的工具，用于模拟晶体介质或因内部位移而变形的地壳等非常不同的材料中的缺陷。我们证明了介质的各向异性可以通过两种方法来解决同一问题，一种是使用积分形式，另一种是附加到均匀介质的格林张量。采用这两种方法对具有较强弹性各向异性的β’CuZn黄铜进行了处理，并对处理结果进行了比较。

An angular dislocation in an anisotropic medium

ABSTRACT The elastic field of an angular dislocation determined by Yoffe ([The angular dislocation. Phil. Mag. 5(50) (1960), pp. 161–175]) using isotropic elasticity is a convenient tool for modelling defects in very different materials such as crystalline media or the Earth’s crust deformed by internal shifts. We show that the anisotropy of the medium can be introduced in two ways to solve the same problem, one using an integral formalism and the other the Green’s tensor attached to a homogeneous medium. β’ CuZn brass, which has a strong elastic anisotropy, is treated with the two methods, and the results are compared.

期刊介绍： Philosophical Magazine Letters is the rapid communications part of the highly respected Philosophical Magazine, which was first published in 1798. Its Editors consider for publication short and timely contributions in the field of condensed matter describing original results, theories and concepts relating to the structure and properties of crystalline materials, ceramics, polymers, glasses, amorphous films, composites and soft matter. Articles emphasizing experimental, theoretical and modelling studies on solids, especially those that interpret behaviour on a microscopic, atomic or electronic scale, are particularly appropriate. Manuscripts are considered on the strict condition that they have been submitted only to Philosophical Magazine Letters , that they have not been published already, and that they are not under consideration for publication elsewhere.
