Viscoelastic Rayleigh waves II [PDF]
Quarterly of Applied Mathematics, 1978 The number of possible surface waves on a viscoelastic half-space is investigated numerically as a function of the material parameters. The results are applied to simple theoretical models of viscoelastic behavior and also to experimental data. It is concluded that two surface waves are possible on some rocks and on nearly all solid polymers.

Bulk and Rayleigh Waves Propagation in Three-Phase Soil with Flow-Independent Viscosity
Applied Sciences, 2022 The flow-independent viscosity of the soil skeleton has significant influence on the elastic wave propagation in soils. This work studied the bulk and Rayleigh waves propagation in three-phase viscoelastic soil by considering the contribution of the flow-

Rayleigh–Taylor shock waves [PDF]
Physics of Fluids, 2007 Beginning from a state of hydrostatic equilibrium, in which a heavy gas rests atop a light gas in a constant gravitational field, Rayleigh–Taylor instability at the interface will launch a shock wave into the upper fluid. We have performed a series of large-eddy simulations which suggest that the rising bubbles of light fluid act like pistons ...

NDE Characterization of Surface Defects on Piston Rods in Shock Absorbers Using Rayleigh Waves
Applied Sciences, 2022 In general, shock absorbers are components that can absorb shock and vibration energy caused by wheel behavior, and they provide handling stability. As a piston rod is an important component in shock absorbers, multiple processes are performed in order ...

Viscoelastic Rayleigh waves [PDF]
Quarterly of Applied Mathematics, 1977 A general analysis is given of the propagation of surface waves over a half-space of homogeneous isotropic linearly-viscoelastic material. Particular emphasis is placed on the properties of the particle paths. The detailed examination of particular models shows that (in contrast with elastic materials) (i) more than one surface wave may be possible ...

Supershear Rayleigh waves at a soft interface [PDF]
, 2013 We report on the experimental observation of waves at a liquid foam surface propagating faster than the bulk shear waves. The existence of such waves has long been debated, but the recent observation of supershear events in a geophysical context has ...

Journal of Physics: Condensed Matter, 2010 Under special kinematic conditions helium atoms impinging upon a crystal surface can be inelastically trapped into a surface bound state and ride the created Rayleigh wave. This special case of phonon-assisted selective adsorption, leading to an atom-phonon bound state (atomic polaron), can explain previously unassigned resonant features observed in ...

Anomalous surface waves from Lop Nor nuclear explosions: Observations and numerical modeling [PDF]
, 1998 Surface waves from the Chinese test site of Lop Nor are analyzed using long-period and broadband stations located at regional and teleseismic distances and at different azimuths. For most azimuths, strong Love waves between 0.02 and 0.045 Hz are observed

Numerical analysis of the dispersion of acoustic Rayleigh waves in a Functionally Graded Piezoelectric half-Space [PDF]
MATEC Web of Conferences, 2022 Considerable attention has been given to the study of the propagation of surface waves in order to improve the efficiency and lifetime of the surface acoustic wave devices such as transducers.
