Rayleigh–Taylor shock waves [PDF]

open access: yesPhysics 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 ...

Wave propagation in nonlocal orthotropic micropolar elastic solids

open access: yesArchives of Mechanics, 2021
The presented paper is concerned with the propagation of Rayleigh waves in an orthotropic nonlocal micropolar elastic half-space. The main aim of the paper is to derive dispersion equations of Rayleigh wave as well as Stroh formalism for the orthotropic ...

Shallow S-wave Velocity Profile Estimation using Surface Velocity and Microtremor HVSR with a Linear Velocity Increase Approach

open access: yesJournal of Mathematical and Fundamental Sciences, 2023
We propose a simple method for 1D S-wave velocity (Vs) profile estimation using a measured surface S-wave velocity (V1) and peak frequency of the observed microtremor horizontal-to-vertical spectral ratio (HVSR).

Viscoelastic Rayleigh waves [PDF]

open access: yesQuarterly 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 ...

Direct measurements of Rayleigh wave acoustoelastic constants for shot-peened superalloys

open access: yesNDT & E international, 2020
In this article, the experimental investigation of the dependency of surface wave (Rayleigh wave) acoustoelastic constants (AEC) on surface treatment parameters and plastic deformation is discussed.

Anomalous surface waves from Lop Nor nuclear explosions: Observations and numerical modeling [PDF]

open access: yes, 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

Atoms riding Rayleigh waves

open access: yesJournal 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 ...

Non-linear enhancement of laser generated ultrasonic Rayleigh waves by cracks [PDF]

open access: yes, 2008
Laser generated ultrasound has been widely used for detecting cracks, surface and sub-surface defects in many different materials. It provides a non-contact wideband excitation source which can be focused into different geometries.

Asymptotic Formulation for the Rayleigh Wave on a Nonlocally Elastic Half-Space

open access: yesVibration, 2023
This paper deals with the Rayleigh wave, propagating on a nonlocally elastic, linearly isotropic half-space, excited by a prescribed surface loading. The consideration develops the methodology of hyperbolic–elliptic models for Rayleigh and Rayleigh-type ...

Horizontal rotation signals detected by "G-Pisa" ring laser for the Mw=9.0, March 2011, Japan earthquake [PDF]

open access: yes, 2012
We report the observation of the ground rotation induced by the Mw=9.0, 11th of March 2011, Japan earthquake. The rotation measurements have been conducted with a ring laser gyroscope operating in a vertical plane, thus detecting rotations around the ...
