Damping of waves in a layered structure composed of two elastic plates coupled by a viscous liquid
Abstract eng: We present a model describing the frequency and damping of waves traveling in a layered structure that is composed of two elastic plates and a viscous liquid layer in between. The wave-shaped perturbations are assumed to be small so that the linearized Navier–Stokes equations adequately describe the incompressible fluid motion. The equations are discretized along the transverse direction which yields an algebraic eigenvalue problem that we solve numerically. We discuss the results for the three modes in the low wavenumber regime.
