Abstract

The fracture problem around the center crack in an infinite transversely isotropic piezoelectric plate under the anti-plane shear stress and the in-plane electric load at infinity is studied. Using the complex function method and undetermined coefficients method, the analytical solutions of the stress, displacement, electric displacement, electric potential, stress intensity factor, electric displacement intensity factor and the mechanical strain energy release rate around the crack tip are obtained with the assumption that the surface of the crack was electrically impermeable. The influence of the crack length, the mechanical load and the electric load on the mechanical strain energy release rate is analyzed with numerical analysis. The results show that the crack length and the mechanical load are always promoting the crack extension, the positive electric field promotes crack extension, and the negative electric field restrains it.
