SH Surface Waves in Functionally Gradient Piezoelectric Plates

Sh-waves in Laminated Plates

A mathematical model for analyzing horizontally polarized shear surface (SH) waves propagating in laminated plates is presented. All the layers are assumed to have monoclinic symmetry. Three types of boundary conditions imposed on the outer surfaces of a plate are considered. A variant of the modified transfer matrix (MTM) method is developed. Closed form dispersion relations are obtained for p...

Piezoelectric Actuators for Functionally Graded Plates- Nonlinear Vibration Analysis

Mathematical Modeling of Thin Piezoelectric Plates with Electric Field Gradient

Piezoelectric materials are widely used in the design of smart structures. It is thus of major technological interest to provide efficient modelings of such structures. In the case of thin piezoelectric plates, classical studies generally lead to two different models. These two models can be linked to the distinction between sensors and actuators. Here, we extend these results to the second ord...

Asymptotic modeling of piezoelectric plates with electric field gradient

We extend our modeling of smart structures to second order piezoelectricity. We show that three different models have to be taken into account, which broadens the scope of the sensors and actuators field. Second order piezoelectricity being compatible with isotropy, we also propose a systematic study of the impact of crystalline symmetries on our models. To cite this article: T. Weller, C. Lich...

Vertically Reinforced 1-3 Piezoelectric Composites for Active Damping of Functionally Graded Plates

M ONOLITHIC piezoelectric materials (PZTs) have been widely used as distributed sensors and actuators for developing smart structures with self-monitoring and selfcontrolling capabilities [1–10]. However, their major drawback is low control authority as the magnitude of their electromechanical coefficients is very small. The situation can be improved by using an active constrained layer damping...
