Abstract
This study investigates the generation of waves due to the incidence of the Rayleigh wave upon the corner of an elastic quarter space. The Rayleigh wave is incident from infinity and travels along one surface of a right-angled wedge. Integral equations are derived by use of the Fourier transform technique and are solved by deforming their integration path along which the integrands vary smoothly in magnitude. Expressions for the energy fluxes of the Rayleigh waves along two free surfaces and the scattered body waves are obtained. Partition of energy fluxes and directivities of the scattered P and S waves are discussed. The scattered S waves are then found to be composed primarily of four kinds of waves as if they were generated from different wave sources. The orbital motions of the particle of the elastic medium are depicted along two free surfaces. The orbit form on the second surface tends to that of the Rayleigh wave more rapidly than on the first surface where the incident Rayleigh wave exists. The comparison with experimental results previously obtained by several authors shows considerably good agreement.
