An asymptotic model of a multimaterial with a thin piezoeletric interphase

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