DAMPING PARAMETERS OF LAYERED PLATES AND SHELLS.
Abstract
The concept of the damping parameter is clearly applicable to all types of layered plates and shells and to all types of vibrations. Thus, expressions for the damping parameters are now available for extensional vibrations of sandwich plates and axially symmetrical vibrations of sandwich cylindrical shells as well as for flexural vibrations of sandwich plates. A comprehensive review of these is given in the present paper. In addition, the damping parameters for the two-layered plate are discussed. They are important because the two-layered plate represents a basic situation in which damping of the vibration of a plate by an added viscoelastic layer was first adopted in practice. In all cases considered, expressions are given for the frequencies together with the damping parameters.
