Electromechanical nonstationary thickness vibrations of a piezoceramic layer

The methods of characteristics and difference schemes are used to study the nonstationary thickness vibrations of a piezoelectric layer polarized across the thickness and subjected to electrical and mechanical loads. The propagation of waves under loading of various types is studied. The dynamic electroelastic state of the layer is analyzed. It is established that the characteristics of the electroelastic state are in a linear relationship
