Wave Propagation in Elastic Layer Placed Between Two Different Fluid Media
要約
Propagation of harmonic waves in a hydroelastic system consisting of the uniform elastic layer between two compressible fluids of different physical properties is investigated. A dispersion equation is derived and analyzed numerically for phase velocities lower than the greater sound velocity of two fluids. The dispersion equation has two real roots close to symmetric and antisymmetric oscillations of the layer loaded by the same fluids from both sides. Limiting case of the same fluids when the problem is splitted into two independent ones, as well as limiting cases of Rayleigh and Stonley waves are considered. The expressions for displacements, shear and normal stresses are obtained. Corresponding wave modes are determined and their properties are analyzed.
