Vibroacoustic analysis of plates with damping patches using a layerwise theory and the Rayleigh-Ritz

Abstract

This work addresses issues on vibration and noise control studying an efficient model to simulate the dynamic and vibroacoustic behavior of plates with constraining-layer damping patches. The proposed model, gathers the advantages of the layerwise models with the number of degrees of freedom of a single-layer theory. In addition, the Rayleigh-Ritz method arises as a reliable alternative to the finite element method and offers a very efficient solution regarding patches handling. Taking advantage of the resourceful solutions that this model offers the efficiency of the damping treatments is analyzed and discussed.
