In this study, we treat analytically a two-dimensional electroelastic problem of an infinite piezoelectric body with two circular piezoelectric inhomogeneities one of which contains a crack. We consider that the body is subjected to anti-plane shear load and in-plane electric load at infinity. The problem is solved based on Bueckner's principle and is finally reduced to a problem of a singular integral equation of the first kind with respect to the distribution function of screw dislocation. Stress intensity factor is formulated. Some numerical results are shown to investigate the influence of micromechanics parameters on electroelastic field and stress intensity factor.
