## This study deals with the determination of natural frequencies of transverse vibrations of simply supported, clamped, and clamped-simply supported beams with an intermediate support subject to an axial force. Results are presented in graphical fashion as a function of the governing geometric an

β¦ Synopsis
An inertia force cancellation method for controlling vibrations of flexible beams subjected to forced vibration loads is presented in this paper. A straightforward method is presented for removing resonances and spillover instabilities. A modal decomposition method is first presented and then the theoretical expression for removing the resonances. Results of numerical simulations are presented for some example problems.

Natural frequencies and buckling loads of a simply supported beam with small length-to-depth ratio and sufficiently thin rectangular cross-sections subjected to initial axial tensile and/or compressive forces are analyzed. By using the method of power series expansion of displacement components, a s

Vibrations in structures can lead to a number of problems, not the least of which can be fatigue failures from excessive long term cyclic stresses. Passive techniques for vibration control, though sometimes limited in their capabilities, have been the primary method used in the past to attenuate vib
