โœฆ Synopsis

This paper formulates and examines the electro!elastic coupling e}ects resulting from the presence of a screw dislocation inside an elliptical piezoelectric inhomogeneity embedded in an in_nite piezoelectric matrix[ The general solution to this problem is obtained by conformal mapping and Laurent series expansion of the corresponding complex potentials[ The appropriate expressions of the _eld potentials and the _eld com! ponents are given explicitly in both the inhomogeneity and the surrounding matrix using a perturbation technique[ The internal energy and the force on the dislocation are computed and several speci_c examples are provided to illustrate the validity and versatility of the developed formulations[

The problem of a screw dislocation inside a circular inhomogeneity incorporating interface stress is investigated. The analytical expressions of the complex potentials, stress fields and the image force acting on the dislocation are obtained by means of the complex variable method. The image force a
