Nonlinear Evolution of Piezoelectric SAWs,2,3], LARDNER [4,5,6], DAVID [7], LARDNER and TUPHOLME [8] and PLANAT [9]. All treatments, using variants on the method of multiple scales, yield an evolution equation equivalent to that first given by LARDNER [4] for the Fourier transform of the waveform. Extensions of the techniques to nonlinear

Finite Amplitude Love Waves on an Incompressible Elastic Layered Half Spacepace is investigated. A nonlinear Schrödinger equation is derived to, govern this motion asymptotically. It is shown that the surface solitary wave may exist depending on the nonlinear constitution of the layered half space.

Nonlinear Surface Acoustic Waves and Their Associated Surface Acoustic Solitonsion that propagate without change of form in a system that consists of a film of thickness d of a linear, cubic elastic medium bonded to a semi-infinite, nonlinear, cubic elastic medium. From the nonlinear dispersion relation we obtain the nonlinear Schrödinger equation governing the propagation of

Aspects of the Behaviour of Surface Waves in Transversely Isotropic Elastic Media body waves in the basic understanding of surface-wave behaviour. As pointed out by CHADWICK and SMITH [1], this connection entails a systematic procedure for determining the nature of surface-wave propagation in elastic media with specified symmetry, beginning with an elastodynamic classification o

Surface Acoustic Waves on Rough Surfacesbe planar in the absence of the roughness, are of three kinds: (a) a planar surface with an isolated protuberance on it; (b) a periodically corrugated surface; and (c) a randomly rough surface. The first kind of roughness gives rise to surface shape resonances, i.e. to modes that are spatially local
