The Caustic of a Rayleigh-Wave
1989The method of caustic or shadow-spot technique is utilized to determine the caustic of a Rayleigh-wave. The size and shape of the caustic allow for characterization of the source of the Rayleigh-wave disturbance .

Rayleigh waves recorded at Lubbock, Texas, from natural earthquakes and from nuclear explosions are compared. Natural earthquakes generate both first-mode and second-mode Rayleigh waves, but the explosions generate only first-mode Rayleigh waves. Absence of second-mode Rayleigh waves from the explosions is related to a lack of SV energy in the source ...

In this chapter, the mechanism for generating fluctuating reservoir pressures will be explored. The generation of surface waves and fluctuating pressures in the upstream reservoir due to gate motion will be examined. The energy input into surface waves is dissipated, or dispersed, as the waves travel away from the structure.

In an elastically isotropic semiinfinite medium having a free surface with a weak harmonic corrugation, the interaction between the Rayleigh wave guided along the free surface and the shear vertical and pressure bulk elastic waves propagating in the substrate is investigated for the propagation directions lying in a plane perpendicular to the average ...

It is now a century since LORD RAYLEIGH published his theoretical proof of the existence of elastic waves propagating along the plane surface of an elastic solid [1]. In reading this paper one is struck by the fact that, except for minor changes in notation, the formulation established by Rayleigh is still followed today in the theory of elastic guided

In modern Rayleigh-wave devices, transducers are needed to generate Rayleigh waves in response to an applied electrical signal and to sense the waves so as to give an electrical output waveform. These are clearly key requirements for electronic devices, and are usually met by using interdigital transducers on piezoelectric substrates.

The Yoffe crack model [I] considers a crack of fixed length propagating with constant speed in an infinite plate under a uniform tensile stress normal to the crack plane. It is assumed that the crack retains its original length during propagation by resealing itself at the trailing end. For this problem the strain energy release rate G is given by $
