Piezoelectric materials are widely used in industrial areas from the excellent characteristic of mechanical and electrical couplings such as the sensors and actuators. 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 electro elastic analysis is performed for transversely isotropic piezoelectric materials containing multilayered elliptical inclusion under several singular loads. General solutions of this study are obtained by using the complex potential functions and conformal mapping technique. And several numerical examples are shown by graphical representation. The effects of some condition of singular loads are discussed.
