Abstract

Abstract

The electroelastic interaction of a piezoelectric screw dislocation with an elliptical inclusion in piezoelectric materials is considered.The electroelastic fields in both the matrix and the inclusion were given explicitly by using the perturbation concept and the method of Laurent series expansion.Furthermore,the expressions of the image force acting on a piezoelectric screw disolcation were obtained.Numerical examples are provided to reveal the effect of piezoelectricity and the relative stiff ness between the inclusion and the matrix on the image force.Consequently,the new interaction mechanism is found.
