Ztráta stability kloubově uložených kuželových skořepin s malým vzepětím zatěžovaných vnějším přetlakem

Abstract

The aim of this paper is to suggest an approximate analytical method that could allow inexpensive and fast computational control of stability of conical shells with lower edge angle = 5° ÷ 15° with hinged lower edge. Standard methods of stability calculation according to European Recommendation ECCS [1] are not applicable due to the geometry of the examined shells. Numerical analyses are performed by FEM computer program COSMOS/M [2].
