Summary

A novel and effective method is proposed to determine the image force acting on a screw dislocation located inside an elastic inhomogeneity of arbitrary shape perfectly bonded to an infinite elastic matrix. The basis for our representation of the image force stems from the fact that the analytic function defined inside the elastic inhomogeneity can be conveniently constructed from the continuity conditions of traction and displacement across the perfect interface. An identical method is employed to derive the image force on a screw dislocation inside a piezoelectric inhomogeneity of arbitrary shape.

概括

提出了一种新颖有效的方法来确定作用在完美结合到无限弹性矩阵上的任意形状的弹性不均匀性内部的螺旋位错上的像力。我们表示像力的基础是基于这样一个事实，即弹性不均匀性内部定义的解析函数可以方便地通过理想界面上的牵引力和位移的连续性条件来构造。采用相同的方法来推导在任意形状的压电不均匀性内部的螺钉位错上的像力。
