On the anomalously low attenuation of the leaky Rayleigh wave in a fluid-filled cylindrical cavity
It is shown that the dispersive Rayleigh wave propagating around a concave cylindrical surface is substantially less attenuated by fluid loading than the corresponding wave on a flat surface. First, the analytical solution for vertically polarized shear wave scattering from a fluid-filled cylindrical cavity is formulated in the time domain, then the signal of interest is gated out and spectrum ...
متن کاملWave Propagation Approach to Fluid Filled Submerged Visco-Elastic Finite Cylindrical Shells
Multi-layer orthotropic finite cylindrical shells with a viscoelastic core in contact with fluids are gaining increasing importance in engineering. Vibrational control of these structures is essential at higher modes. In this study, an extended version of the wave propagation approach using first-order shear deformation theory of shell motion is employed to examine the free vibration of damped ...
متن کاملSeismic Wave Attenuation in Fluid-saturated Porous Media
Contrary to the traditional view, seismic attenuation in Biot's theory of uid-saturated porous media is due to viscous damping of local (not global) pore-uid motion. Since substantial inhomogeneities in uid permeability of porous geological materials are to be expected, the regions of highest local permeability contribute most to the wave energy dissipation while those of lowest permeability do...
متن کاملWave front dispersion due to fluid-structure interaction in long liquid-filled pipelines
Half a century ago Richard Skalak (1923-1997) (Ref 1) published a paper with the title "An extension of the theory of water hammer" (Refs 2, 3, 4), which has been the basis of much subsequent work on hydraulic transients with fluid-structure interaction. The paper considers the propagation of pressure waves in liquid-filled pipes and the coupled radial/axial response of the pipe walls. In a tri...
متن کاملStoneley Wave Propagation in a Fluid-filled Borehole with a Vertical Fracture
The propagation of Stoneley waves in a fluid-filled borehole with a vertical fracture is investigated both theoretically and experimentally. The borehole propagation excites fluid motion in the fracture and the resulting fluid flow at the fracture opening perturbs the fluid-solid interface boundary condition at the borehole wall. By developing a boundary condition perturbation technique for the...
