PLATE DAMPING DUE TO THICKNESS-COMPRESSION WAVES IN ATTACHED VISCOELASTIC LAYERS
Abstract
The purpose of the present report is to propose and attempt to validate an additional mechanism for energy dissipation in the viscoelastic layer in order to account for damping increases. The mechanism proposed is associated with waves propagating in the thickness direction, and the damping peaks are ascribed to corresponding standing wave resonances. The governing equations are derived in the first of the following sections; thereafter theoretical predictions are compared with experimental results. Conclusions are summarized and extensions of the present work are discussed. (Author)
