Abstract

A theoretical description of ideal and viscous fluid media is exploited to address the problem of modelling damping effects of any guided elastic waves at the interface between viscous fluids and solids. It is based on a boundary element method (BEM) using the Green's function of the considered media mixed with finite element analysis (FEA). This approach is used to compute an harmonic admittance from which propagation characteristics can be extracted. The influence of acoustic radiation and viscosity effects on different kind of waves excited on various substrates is reported and discussed.
