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

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 $

Rayleigh Waves on Curved Surfaces
The Journal of the Acoustical Society of America, 1969Rayleigh waves, which are elastic surface waves occurring at the interface between a solid elastic body and vacuum, are investigated. The exact solution of some canonical elastodynamic problems in a circular cylindrical geometry is given, from which the Rayleigh wave contribution is isolated.

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 ...

Acoustoelectronic Rayleigh Wave Devices
1985Electrons or charged particles can be made to interact with the electric fields of Rayleigh waves in piezoelectric crystal surfaces. The charged particles can be in vacuum, in semiconductors or bound to traps in solids or on surfaces. During the past two decades a large variety of acoustoelectronic amplifiers, signal processors and image processing ...

Waves passing through physical structures provide a convenient means for achieving analog approximations to the mathematical operations of convolution and correlation. Because the waves propagate from one position to another, they provide a natural scan through the structure synchronous with the flow of time.
