Asymptotic modeling of a thin anisotropic piezoelectric interphase

We study the electromechanical behavior of a thin interphase, constituted by a linearly piezoelectric anisotropic material 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. Moreover, we identify the non classical electromechanical transmission conditions at the interface between the two three-dimensional bodies.
