ABSTRACTAn analysis is presented for wave propagation in infinite homogeneous elastic plates of piezoelectric materials. The analysis is an extension to the work by Shuvalov [1] on wave propagation in general anisotropic elastic plates. A real form of dispersion equation is provided for a piezoelectric plate subjected to different boundary conditions on the plate surfaces. Perturbation theory [2] is exploited to obtain long-wavelength low-frequency approximation for physical quantities of wave propagation, including wave amplitude, stress, electric potential, electric displacement and velocity.

The problems of coupled physical fields, such as the interaction of mechanical and electromagnetic fields, piezoelectric effect, electrostriction and others, are the most urgent. The study of the issues of wave propagation in piezoelectric materials is also relevant. In this paper the propagation of a monochromatic electroelastic signal in a semi-infinite piezoelectric layer is considered. Let's consider different cases of the boundary conditions, from which localized vibrations can be obtained in the vicinity of the free edge.

The Impact

The aim of this paper is to present the method of identifying the impact location on the plate. This basic research has the purpose to achieve the human-interaction technology based on the signal processing, piezoelectric materials, and wave propagation. The work concerning the location identification of a single impact on the plate has been previously studied by means of the time frequency analysis applied to accelerometer signals. In this paper, a novel approach for the location identification of the discrete impact is presented to investigate the feasibility of applying to a human-interaction system. For the identification of the impact location, the major axisymmetry mode of the Lamb wave on the plate is used for this work and Kalman filter tracking is employed.

In this paper, the analytical and numerical studies of two-dimensional wave propagation in porous piezoelectric materials (PPMs) are carried out. The decoupling of waves, in such materials for various crystal classes, is studied analytically for different coordinate planes. It is found that, for wave propagation in a plane, the system is decoupled in some crystal classes, whereas it remains coupled in other crystal classes. It is established that the decoupled pure-shear wave, propagating in a PPM, can be stiffened or unstiffened with piezoelectric effects even if the PPM belongs to the same symmetry group but has a different crystal class. The skewing angles and mutual angles between the polarization directions of different waves are also computed numerically.
