Abstract

This article is devoted to the non-stationary modes of radiation of acoustic waves by piezoceramic layer that contacts with an ideal compressible liquid and limited to the hard surface. The statement of problem and method of task solution is executed. A task is solved with the use of Laplace time integral time transformation.

Formulas are obtained for determination of physical  descriptions of the investigated \ transient process, such as hydrodynamic pressure, mechanical tension, wave potential, moving of piezoceramic layer and electric potential
