Rayleigh waves in symmetry planes of crystals: explicit secular equations and some explicit wave speeds [PDF]
, 2012 Rayleigh waves are considered for crystals possessing at least one plane of symmetry. The secular equation is established explicitly for surface waves propagating in any direction of the plane of symmetry, using two different methods.

Modeling linear Rayleigh wave sound fields generated by angle beam wedge transducers
AIP Advances, 2017 In this study, the reciprocity theorem for elastodynamics is transformed into integral representations, and the fundamental solutions of wave motion equations are obtained using Green’s function method that yields the integral expressions of sound beams ...

Seismic seiche-related oscillations in Lake Biwa, Japan, after the 2011 Tohoku earthquake
Scientific Reports, 2022 Seismic seiche-related oscillations caused by Rayleigh waves from large earthquakes are yet to be explored and elucidated comprehensively, then need to accumulate continuously.

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.

Reference free imaging of subsurface cracks in concrete using Rayleigh waves
Structural Control & Health Monitoring, 2018 One of the major reasons of deterioration in reinforced concrete structures is cracking of the concrete cover. In contrast to bulk waves, ultrasonic Rayleigh waves are more sensitive to such near‐surface cracks.

Rayleigh waves, surface disorder, and phonon localization in nanostructures [PDF]
, 2015 We introduce a technique to calculate thermal conductivity in disordered nanostructures: a finite-difference time-domain (FDTD) solution of the elastic wave equation combined with the Green-Kubo formula.

Signal enhancement of the in-plane and out-of-plane Rayleigh wave components [PDF]
, 2005 Several groups have reported an enhancement of the ultrasonic Rayleigh wave when scanning close to a surface-breaking defect in a metal sample. This enhancement may be explained as an interference effect where the waves passing directly between source ...

Thermo-visco-elastic Rayleigh waves under the influence of couple-stress and gravity
International Journal of Mathematics and Mathematical Sciences, 1991 This paper is concerned with thermo-visco-elastic Rayleigh waves under the influence of couple-stresses and gravity. A more general phase velocity equation for these waves is derived.
