Abstract:

Strain-displacement relations are developed for a thin truncated circular conical shell and its reinforcing rings and stringers. Using these relations in an energy approach, methods are developed for determining the resonant frequencies of simply-supported conical shells in unstiffened, ring-stiffened, or ring-and-stringer-stiffened configurations. The stiffeners may be either widely-separated or closely-spaced. Results obtained using these methods are compared with experimental data available in the literature for unstiffened and ring-stiffened shells and data collected in tests of ring-stiffened and ring-and-stringer-stiffened conical shells.
