BUCKLING OF CIRCULAR CONICAL SHELLS UNDER COMBINED TORSION AND EXTERNAL OR INTERNAL PRESSURE,
Abstract
A method developed previously for the analysis of the instability of thin conical shells under external pressure is now extended to buckling under torsion and combined torsion and external or internal pressure as well as axisymmetric temperature distributions. The method is based on solution modified Donnell type stability equations, in the presence of slightly relaxed boundary conditions for the u and v displacements. Two formulations of the solution for torsion and combined loadings are given and compared. Typical examples are calculated and compared with results obtained by Seide and tests, and interaction curves for combined torsion and external and internal pressure loading are given and compared with experimental curves. For conical shells of small and medium taper ratio, the interaction curves may be approximated by the semi-empirical curve of Crate, Batdorf and Baab for cylindrical shells, but for larger taper ratio different curves are obtained.
