Free vibration of beams with intermediate point supports is studied by the classical Ritz method within the context of Euler beam theory. For the Ritz method, the displacement of a beam is approximated by a set of admissible trial functions which must satisfy the kinematic conditions at the ends and

โฆ Synopsis
In the work presented here, a method is developed to predict the stationary random response of a beam which has been modi"ed by the attachment of a damped, lumped assembly of linear mechanical elements. The initial development treats a general beam system with attached linear elements. Two examples are presented with a cantilever beam modi"ed, respectively, by a tip damper and a damped vibration absorber attached at the tip. The attached vibration absorber presents an interesting optimization problem to "nd the damping that minimizes the mean-square motion at the beam tip.

A new type of self-damping system--an elastic beam with a sliding washer-is analyzed. It is found that under external excitation the motion of the washer sliding along the beam can eliminate resonances, and decrease the beam's dynamic response to random stationary and impulsive excitation.

A new analytical, energy based approach is described that predicts the harmonic vibration response of a damped beam with multiple viscoelastic patches. Each damping patch consists of a metallic constraining layer and an adhesive viscoelastic layer with spectrally-varying material properties. Since t
