Notes:
A two-dimensional electromechanical analysis is performed on a transversely isotropicpiezoelectric material containing a line crack of length 2a, which is subjected to uniform distributedforces with intensity q along the crack faces and uniform electric displacement fields at infinity.Based on the impermeable electric boundary conditions, the closed complex form expression for theelectromechanical fields are deduced in the vicinity of the crack. Taking PZT-4 ceramic intoconsideration, electromechanical fields under different loads are illustrated through several examples.It can be seen that electromechanical fields show 1/2 order singularity at the crack tip, and thepiezoelectric effect can’t be negelected
