The electro-mechanical fracture problem of a piezoelectric strip containing a T-shaped crack is considered in this study. The problem is solved for a piezoelectric strip that is under electromechanical loadings. The crack faces are supposed to be completely insulated. By using the Fourier transform, the electromechanical problem is reduced to a system of singular integral equations. The singular integral equations are solved numerically. Numerical calculations are carried out, and detailed results are presented to illustrate the influence of the electro-mechanical interaction on the stress and electric displacement intensity factors. From the numerical results, we can find that the normalized stress and electric displacement intensity factors are under the great influence of the geometric parameters.
