Abstract

In this paper, electromechanical analysis is performed based on an extended Stroh formalism which considers the constitutive law of a linear anisotropic piezoelectric medium, the kinematics of two-dimensional small deformations and static equilibrium. By this formalism, several analytical closed-form solutions are obtained for holes, cracks or interface cracks in an infinite piezoelectric medium under various loading conditions. To have a practical use for engineering analyses, the Green's functions obtained from point load condition are embedded into the usual boundary integral equations. Thus, a special boundary element is developed to deal with the problems with finite boundaries.
