Abstract: | By using Stroh' complex formalism and Cauchy's integral method, the electro-elastic fundamental solutions of an infinite anisotropic
piezoelectric solid containing an elliptic hole or a crack subjected to a line force and a line charge are presented in closed
form. Particular attention is paid to analyzing the characteristics of the stress and electric displacement intensity factors.
When a line force-charge acts on the crack surface, the real form expression of intensity factors is obtained. It is shown
through a special example that the present work is correct.
