Abstract

The electromechanical fracture problem of a piezoelectric strip containing two coplanar cracks are considered in this study. The problem is solved for a piezoelectric strip that is under a uniform mechanical load far away from the crack region. By using the Fourier transform, the problem is reduced to a system of singular integral equations. The singular integral equations are solved by using the Gauss-Jacobi integration formula. Numerical calculations are carried out, and detailed results are presented to illustrate the influence of the parameters of indicating the crack lengths and the crack locations on the stress intensity factors. From the numerical results, we can find that the normalized intensity factor are the great influence of the geometric parameters.
