thin elastic plate, elastic band, longitudinal and shear vibrations, energy-flux vectorAbstract
The forced vibrations of a thin elastic band excited by a point source have been considered. The vibration processes are described by the equations of thin plate theory. An integral representation of the displacement field is derived. A normal wave expansion of the displacement field is carried out. It is shown that the inverse wave exerts a strong influence on the character of the energy flux behavior.
