Fluid Layer between Infinite Elastic Plates. I. Mathematics and Intensity Vectors.

Abstract

The pressure and displacements, due to line-force and line-source excitation, are given in terms of Fourier integrals which can be evaluated numerically. Plots of intensity vectors provide a vivid illustration of the energy flow in the fluid. The selected plots show significant interchange of propagating energy between fluid and the driven plate when the excitation is a force, but not when the excitation is a source. (Author)
