On a Hyperbolic Equation for the Rayleigh Wave
, 2023 A 1D hyperbolic equation is derived for the Rayleigh wave induced by prescribed surface loading. The wave operator turns out to be independent of the vertical coordinate, which appears only in the right hand side of the equation as a parameter within the

Asymptotic Formulation for the Rayleigh Wave on a Nonlocally Elastic Half-Space
Vibration, 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]
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.

Bio-Inspired Gradient Coatings Enhance the Leading Edge Erosion Resistance of Wind Blades. [PDF]
Adv Sci (Weinh)Rain‐induced erosion of the wind turbine blade leading edge poses a critical challenge to maintenance and operation. Here, we propose a bio‐inspired approach for erosion protection utilising a platelet‐reinforced polyurethane coating with a graded through‐thickness architecture.

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

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 ...

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