    Abstract: In this paper, the scattering of acoustic waves by 3-D finite axisymmetric shells immersed in a fluid is analyzed. The governing equations for axisymmetric shells are derived by including the effects of rotary inertia terms and the dynamic impedance of the shell is then evaluated numerically and incorporated into the T-matrix formalism. Using the T matrix thus computed the farfield scattering is evaluated. Numerical results will be presented for the backscattered amplitude as a function of frequency for a finite cylindrical shell with hemi-spherical endcaps for different angles of incidence. This new semi-analytical method will be compared with the finite element method for incidence along the axis of the shell.

    Acoustical Society of America (ASA) ; 1983

    Abstract: The scattering of acoustic waves by an infinitely long cylindrical shell immersed in a fluid is analyzed. A new approach has been proposed using thin shell theory; incorporating the impedance of the shell in the T-matrix formulation. Numerical results are presented for the farfield back scattering amplitude as a function of frequency. Calculations were made for infinitely long circular and elliptic cylindrical shells immersed in water for various shell thicknesses, for waves incident at an arbitrary angle in the plane normal to the axis of the cylinder. The impedance resulting from the use of various shell theory approximations for circular cylindrical shells is presented. Love-Timoshenko and Flugge-Byrne-Lurye theories for circular cylindrical shells have been compared with the full elasticity solution using the separation of variables approach. Comments have been made regarding the range of applicability of various shell theories.
