By using Stroh’ complex formalism and Cauchy’s integral method,the electro-elastic fundamental solutions of an infinite anisotropic piezoelectric solidcontaining an elliptic hole or a crack subjected to a line force and a line charge arepresented in closed form.Particular attention is paid to analyzing the characteristicsof the stress and electric displacement intensity factors.When a line force-charge actson the crack surface,the real form expression of intensity factors is obtained.It isshown through a special example that the present work is correct.
