Abstract
In a previous paper, the authors developed a formulation for mathematically modeling the scattering of plane acoustic waves by an elastic body, and results were presented for the scattering of normally incident plane waves from a disk. In this paper, results are presented for scattering of obliquely incident plane waves from the same disk. Total scattering cross sections are calculated as functions of frequency and incident angle. For an incident wave angle of 60°, the calculated displacement distributions on the disk are decomposed into the disk’s free vibrational eigenmodes at selected frequencies. The scattering patterns of total pressure and of scattered pressure and contour plots of the nearfield pressure distributions are also presented for frequencies of interest. Subject Classification: 30.35, 30.40, 30.30.
