| Abstract: | Summary In this paper, we study a two-dimensional electroelastic problem of an infinite piezoelectric body with two circular piezoelectric
inhomogeneities, one of which contains a crack. We formulate the stress intensity factor (SIF) analytically and investigate
it numerically. The problem is solved based on Bueckner's principle, and is reduced to a problem of a singular integral equation
of the first kind with respect to the distribution function of screw dislocation. The effect of interaction between the two
inhomogeneities and the crack on the electroelastic field as well as the control of the SIF by electrical loads is investigated.
