Stability Assessment of Complex Shell Structures by Numerical Analysis

Research output: Contribution to journalArticlepeer-review


This paper discusses the difficulties and pitfalls for the designer in directly using computer-based numerical buckling analysis in stability design and assessment of thin shells with a complex geometry or under complex loading conditions. The different types of buckling analysis are described, and their advantages and disadvantages examined. Methods for relating the buckling load from a numerical analysis to the probable real strength of the structure are then discussed, with particular emphasis on the strong influence of small fabrication imperfections in the geometry. Finally, some common pitfalls in numerical buckling analysis are described and their implications clarified.
