Electroelastic effect induced by electrode embedded at the interface of two piezoelectric half-planes

Following the theory of linear piezoelectricity, we consider the static behavior of the elastic and electric variables in the vicinity of an internal electrode embedded at the interface of two dissimilar piezoelectric half-planes. Fourier transforms are used to reduce the mixed boundary value problem to the solution of a pair of dual integral equations. The integral equations are solved exactly, and the displacement and electric potential are expressed in closed form. The solution is also obtained for bonded piezoelectric and elastic half-planes with an electrode embedded at the interface. Numerical values on the stress and electric displacement are obtained, and the results are plotted to display the electroelastic interactions.
