Asymptotic analysis of a multimaterial with a thin piezoelectric interphase

We study the electromechanical behavior of a multimaterial constituted by a lin- ear piezoelectric transversely isotropic plate-like body with high rigidity embedded between two generic three-dimensional piezoelectric bodies by means of the asymptotic expansion method. After defining a small real dimensionless parameter ε, which will tend to zero, we characterize the limit model and the associated limit problem. We give also a mathemati- cal justification of the model by means of a functional convergence argument. Moreover, we identify the non classical electromechanical transmission conditions between the two three-dimensional bodies.
