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-

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.

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 ...

Disturbances of surface wave field due to wave scattering at shallow cavities
Yantu gongcheng xuebao, 2018 In homogenous half spaces, the wave fields at shallow depth are dominated by Rayleigh waves activated by the surface sources. When the forward Rayleigh waves encounter a shallow cavity, the displacement shapes and the particle orbit are changed. Rayleigh

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 ...

Rayleigh-wave coupling to atmospheric compression waves* [PDF]
Bulletin of the Seismological Society of America, 1952 AbstractThe theory of dispersive Rayleigh waves coupled to atmospheric compressional waves is derived for the case of a solid surface layer. Numerical computation of phase and group velocity curves indicates that an additional branch may be introduced to the dispersion curves as a result of air coupling.

Rayleigh–bloch waves in CMUT arrays [PDF]
IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2014 Using the small-signal electrical equivalent circuit of a capacitive micromachined ultrasonic transducer (CMUT) cell, along with the self and mutual radiation impedances of such cells, we present a computationally efficient method to predict the frequency response of a large CMUT element or array.

Supershear Rayleigh Waves at a Soft Interface [PDF]
Physical Review Letters, 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 inspired us to search for their existence in a model viscoelastic system. An optimized fast profilometry
