Abstract
The problem of Rayleigh wave scattering in a homogeneous, isotropic wedge by experimental means was investigated. For an incident Rayleigh wave, reflected and transmitted Rayleigh waves are generated, as well as longitudinal and transverse cylindrical bulk waves initiated by the virtual source at the corner line. Sector‐shaped test pieces were used, which focused back the diverging bulk waves to the same corner line after normal reflection at the cylindrical surface. By this simple geometry, both the phase and amplitude of all four components were able to be measured. Experimental results are presented to show the varying energy partition among these modes as a function of wedge angle from 90° to 150° in aluminum. Furthermore, the Rayleigh wave reflection and transmission results are compared to recent theoretical predictions by Gautesen [Wave Motion 9, 51–59 (1987)].
