Wave Propagation in A Sandwich Plate Loaded by A Viscous Compressible Fluid

Chubinskiy, A.V. / Sorokin, S.V.

Abstract This paper addresses wave propagation in an unbounded elastic sandwich plate loaded by a layer of viscous compressible fluid. The dispersion equation is derived and the location of dispersion curves as a function of the depth parameter is analyzed. The viscosity-induced attenuation of waves in this wave guide is compared with the wave attenuation in a rigid duct filled with a viscous fluid and in a similar wave guide, where a sandwich plate is replaced by a conventional Kirchhoff plate.
