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 ...

Rayleigh-wave coupling to atmospheric compression waves* [PDF]

open access: yesBulletin 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]

open access: yesIEEE 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]

open access: yesPhysical 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

Rayleigh Waves in a Rotating Orthotropic Micropolar Elastic Solid Half-Space

open access: yesInternational Journal of Geophysics, 2013
A problem on Rayleigh wave in a rotating half-space of an orthotropic micropolar material is considered. The governing equations are solved for surface wave solutions in the half space of the material.

The axisymmetric Rayleigh waves in a semi-infinite elastic solid

open access: yesTheoretical and Applied Mechanics Letters, 2020
: It is well-known that Rayleigh wave, also known as surface acoustic wave (SAW), solutions in semi-infinite solids are plane waves with signatory properties like the distinct velocity and exponentially decaying deformation in the depth.

Study of high-resolution analysis of Rayleigh waves on the basis of the Choi–Williams distribution

open access: yesFrontiers in Earth Science
Rayleigh wave exploration is widely used in the field of engineering investigation, which can analyze the near surface velocity structure. However, the traditional Rayleigh wave exploration data processing method can only provide the average change of ...
