On étudie le comportement électromécanique d'un multimatériau constitué d'un corps de type plaque piézoélectrique isotrope transverse de grande rigidité inséré entre deux corps 3D piézoélectriques génériques à travers la méthode des développements asymptotiques. Après avoir défini un petit paramètre adimensionnel ε qui tend vers zéro, on caractérise le modèle limite et son problème limite associé. De plus, on identifie les conditions de transmission éléctroméchaniques non classiques entre les deux corps 3D.

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 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 between the two three-dimensional bodies.
