摘要
将压电材料的电渗透型裂纹处理成静电学的连接界面，按裂纹上、下两表面的切向电场强度连续和法向电位移连续建立了裂纹处的电渗透边界条件．据此，用复变函数方法，得到了压电材料反平面裂纹问题的精确解．
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.
