Abstract :
Experimental results are presented revealing the characteristics of wedge waves propagating along the edge of free and immersed curved elastic wedges with variable cross section and range-dependent apex angle. Broadband pulsed wedge waves from the elliptical edge of obliquely cut solid cylinders and boreholes are compared. The velocity and number of existing edge modes continuously vary along the wave path. Leaky edge waves radiate in the water with continuously varying angles depending on the local edge wave velocity. Antisymmetric edge waves remained nearly nondispersive over a wide frequency range. The new findings provide physical insight in understanding range-dependent liquid/solid wave phenomena and propeller noise
