Running elastic waves are widely used in the monitoring of various industrial projects to identify damages. Piezoceramic actuators are usually used to generate high-frequency waves for non-destructive testing. Simulation of the elastic wave propagation in mechanical structures is an important task for the development of non-destructive testing and structural condition monitoring of composite materials, which are increasingly used in such fields as aircraft building, chemical industry, pipeline systems, etc. The aim of this study is to determine the displacement field  caused by harmonic vibrations of a piezoelectric plate glued on the upper surface of the isotropic waveguide by means of two methids: Fourier transform and finite element (FE) method.
