BUCKLING OF CIRCULAR CONICAL SHELLS UNDER AXISYMMETRIC EXTERNAL PRESSURE,
Abstract
The stability equations for thin conical shells derived by Seide (J. Appl. Mechanics, 24, No. 4, 547; Dec 1957) are solved for loading under hydrostatic pressure and lateral pressure varying in the axial direction. The solution implies slightly relaxed boundary conditions for the u and v displacements, but for the w displacements the usual conditions of simple supports are enforced rigorously. The stability equation in the radial direction is rederived in a modified form similar to that given by Batdorf (NACA Report 874, 1947) for cylindrical shells and is solved by the Galerkin method. Results for the case of hydrostatic pressure are compared with those obtained by Hoff (AFDSR TR (Final) 59203, Dec 1959) in an analysis restricted to small cone angles, and with the results found by other investigators.
