THE STABILITY OF THIN CONICAL FRUSTUMS SUBJECTED TO AXIAL COMPRESSION AND INTERNAL OR EXTERNAL UNIFORM HYDROSTATIC PRESSURE
Abstract
Calculations are presented for the problems of the stability of conical shells subjected to (1) combined external uniform hydrostatic pressure and axial tension or compression, and (2) combined internal uniform hydrostatic pressure and axial compression. The interaction curves for the first problem are found to depend on the ratio of the end radii of the cone and are bounded by the limiting curves for a cylinder and for a complete cone. The change of shape of the curves with varying end radius ratio is small, however. For the second problem the critical axial load of a pressurized cone is found to be greater than the sum of the critical axial load of an unpressurized cone and the pressure load on the small cross section. The difference is a function of the internal pressure and of the cone geometry. (Author)
