The problem was formulated through Fourier transform into three pairs of dual integral equations, in which the unknown variables are the displacement jumps across the crack surfaces. To solve the dual integral equations, the displacement jumps across the crack surfaces were directly expanded as a series of Jacobi polynomials. Finally, the effects of the shape of the rectangular crack and the distance between two rectangular cracks on the stress and electric displacement intensity factors in a piezoelectric material were analyzed. These results can be used for the strength and the coupling effect evaluation of cracked piezoelectric materials.
