| Abstract: | in this paper, he electrically permeable slit crackwithin a piezoelectric body is treated as a bonding interface inelectrostatics. According to the continuous condition of thetangent component of the electric field strength and the normalcomponent of the electric displacement along the interface,electrically permeable boundary condition is given. Usingsuch boundary conditions, the problems of anti-plane strain ofthe piezoelectric materials with crack are exact analyzed. |
