The vibration and buckling characteristics of cantilever truncated conical shells were studied using a finite element computer program for ring-stiffened shells of revolution. For vibration modes having less than two circumferential waves, the frequencies decreased when the size of a support ring at the free end was increased, while, for modes with several circumferential waves, the frequencies initially increased rapidly when the ring size was increased and then became relatively insensitive to further increase in ring size. It was also shown that conditions at the free end have pronounced effects on the buckling external pressure. Results compare favorably with available experimental data.
