SOUND SCATTERING OF A STEADY STATE PLANE WAVE BY A HOLLOW CYLINDER OF ARBITRARY THICKNESS,
Abstract
An investigation was undertaken to gain insight into the problem of detecting a deep diving submarine by acoustic means. The simplified model chosen to represent the submarine hull was a hollow cylinder. Previous investigators of underwater sound scattering problems represented the structural model within the scope of the technical theory of thin shells. Because of the greater structural strength requirements of a deep diving submarine, the structural model representing the scatterer is a hollow cylinder of arbitrary thickness. Thus, an opportunity to study the influence of the wall thickness on the scattered field is provided. The scattered wave in the fluid field is obtained from the equations of the theory of elasticity. It was found that the wall thickness of the cylinder exerts a significant influence on the scattered plane waves. (Author)
