Evaluation of the Relative Importance of Circumferential or Creeping Waves in the Acoustic Scattering from Rigid and Elastic Solid Cylinders and from Cylindrical Shells.

Abstract

The relationship is determined between predicted circumferential waves on cylinders and the normal-mode series solution for the acoustic scattering by submerged metal cylinders. Specific circumferential waves are linked to the free modes of vibration of the cylinder, and this identification is used to experimentally detect the Rayleigh surface wave at low ka. Circumferential waves on thin cylindrical shells are demonstrated to closely follow prediction based on Lamb theory for flat plates. (Author)
