Abstract
In this paper, we examine the steady state dynamic behavior of an eccentric crack moving at constant velocity in a piezoelectric ceramic layer bonded between two orthotropic elastic layers under the combined anti-plane mechanical shear and in-plane electrical loadings. We adopted permeable crack surface condition. Fourier transforms are used to reduce the problem to the solution of two pairs of dual integral equations, which are then expressed to a Fredholm integral equation of the second kind. The initial crack propagation orientation for a piezoceramic is predicted by maximum energy release rate criterion. Some numerical results for the dynamic stress intensity factor, the dynamic energy release rate and the crack sliding displacement are also presented to show the effects of the crack propagation speed, the crack length, and the electromechanical coupling coefficient.
