Free and Forced Vibrations of a Spinning Viscoelastic Beam
Journal of Vibration and Acoustics, 1996The free and forced response of spinning, viscoelastic, Rayleigh shafts is studied. Viscoelasticity is included using the three parameter solid model. The closed form polynomial frequency equation and integral expressions for the response to a general forcing function are derived. A convenient decay parameter is described. Results are given for natural

Free and forced vibration of a multisupported string
The Journal of the Acoustical Society of America, 1998This paper examines a simple model: the vibration of an infinite string resting on sets of periodic supports, which are modeled as linear spring-mass-damper systems. The qth set of periodic supports may be offset by a distance xq. These offsets can thus be used to create spatially distributed gratings along the length of the string.

Free and forced in-plane vibration of rectangular plates
The Journal of the Acoustical Society of America, 1998A mathematical model is developed for the prediction of the forced response of finite plates to in-plane point force excitations. The model illustrates the nature of the coupling between in-plane longitudinal and in-plane shear waves and the resonant characteristics of the in-plane vibrational behavior of finite flat plates.

Free and Forced Vibrations of Fuzzy Structures
2016Stochastic free and forced vibrations of layered beams are analyzed that result from a single bounded random stiffness parameter whose probability density function is considered to be zero outside of a given interval, i.e., it is a member of a fuzzy set with bounded uncertainty.

Free and Forced Vibration of a Kinked Cantilever Beam
Volume 7A: 17th Biennial Conference on Mechanical Vibration and Noise, 1999Abstract In this paper we use the assumed modes method to derive an analytical model of a kinked cantilever beam of unit mass carrying a kink mass (mk) and a tip mass (mt). The model is used to study the free and forced vibration of such a beam.

Free and Forced Vibrations of Turbine Blades
1988The free and forced vibrations of turbine blades are considered. First, various models for the description and the calculation of their dynamical behaviour are presented and methods of solution are discussed. Second, results and parametric studies are considered which show the influence of the most important blade parameters on the vibrations.

Free and forced vibrations of hollow elastic cylinders of finite length
The Journal of the Acoustical Society of America, 2014An analytical model of axisymmetric vibrations of hollow elastic circular cylinders with arbitrary boundary conditions is presented. Free vibrations of cylinders with free or fixed boundaries and forced vibrations of cylinders with specified non-uniform displacement or stress on the boundaries are considered.

Free and Forced Longitudinal Vibrations of a Cantilevered Bar With a Crack
Journal of Vibration and Acoustics, 1992Longitudinal vibrations of a cantilevered bar with a transverse crack are investigated. For undamped, unforced vibrations, frequency spectra are computed and the effects of the crack location and compliance on the fundamental natural frequency are determined.
