在本文中，我们期待在一个无限的各向同性全空间的环位错（循环）。位错的方向是轴向或径向。与平面分析中的位错不同，路径切割对弹性场有显著影响。给出了各种路径切口的位错解以及位移场和应力场的封闭形式表达式。当单独考虑这些位错不遵守弗兰克的规则，这些异常和其他基本属性进行了讨论。
In this paper we look at ring dislocations (circular loops) in an infinite isotropic full-space. The dislocation direction is either axial or radial. Unlike dislocations in plane analysis the path cut has a significant effect on the elastic fields. Solutions for the dislocations are given for a variety of path cuts with closed form expressions for the displacement and stress fields. When considered alone these dislocations do not obey Frank’s rule; these anomalies and other fundamental properties are discussed.
