Abstract

The steady-state nonaxisymmetrical response of a circular plate and an annular plate with internal damping to a sinusoidally varying force is determined by the modal analysis. The transverse deflection of the plates is expressed by use of the Green function of the plates, and the driving-point impedance and transfer impedance are obtained analytically. The method is applied to a simply supported circular plate and a free-clamped annular plate driven at an arbitrary point; these responses of the plates are calculated numerically, and the effects of the internal damping and the location of the driving point on them are discussed.
