In this paper, two-dimensional electro elastic analysis are performed for isotropic piezoelectric materials containing multilayered elliptical inclusion under anit-plane mechanical and in-plane electrical loads at infinity. It is assumed that the most inner inclusion has a slit crack or a rigid line inhomogeneity and the former slit crack is impermeable to electric fields. The problem of confocal multi-layered elliptical inclusion with perfect and/or imperfect interphases are considered Under the four cases of combined electric and mechanical loadings, various intensity (singularity) factors of Mode III are treated in this paper. General solutions are provided in terms of complex functions and several numerical examples by graphical representation.
