Abstract:
The differential equations governing the free axisymmetric extensional vibrations of an elastic prolate spheroidal shell submerged in an infinite acoustic medium are obtained in prolate spheroidal coordinates using Hamiltons principle. Solutions are obtained by a perturbation technique which converges well for shells of small eccentricity. Numerical results are presented for the fundamental mode, frequency and acoustic impedence of steel shells in water for ratios of major to minor axis up to 1.23 over a wide range of shell length to thickness ratios.
