Piezoelectric materials are widely used in industrial areas from the excellent characteristic of mechanical and electrical couplings. On the other hands, cavities, inclusions, and dislocations in the materials affect fracture and strength of materials. So it is important to analyze mechanical and electrical fields around these defects. In this paper, two-dimensional electroelastic analysis is performed for transversely isotropic piezoelectric materials containing sliding elliptical boundary. General closed-formed solutions are obtained by using the complex potential functions and conformal mapping technique. And several numerical examples are shown by graphical representation.
