Visualization of Plane-Strain Vibration Modes of a Long Cylinder Capable of Producing Sound Radiation

Abstract

This paper points out that a class of plane-strain vibration modes in an isotropic solid cylinder has properties suitable for interaction with a sound field in a fluid medium surrounding the cylinder. A resonance-type theory of such modes is presented. Experimental verification of this theory is obtained by observing stress birefringence patterns of resonating glass cylinders. The circumferential waves arising from these modes are likely to play a part in the scattering phenomena occurring in the medium surrounding the cylinder.
