SUMMARY
The large discrepancies between observed buckling loads for thin shells and the predictions of the classical
theory have been a great challenge to many researchers since the 1920s. In this paper, the basic behaviour
and characteristics are described and recent research, mainly from the last 10 years, is reviewed. The focus
is on cylindrical shells and on the influence of initial imperfections on the buckling behaviour. Copyright #

1. INTRODUCTION
Shell structures represent one of the most efficient ways to transmit forces. They are therefore
widely used, especially when low weight is an important issue. The literature on shell instability
problems is vast. In order to reduce the length of this survey only certain classes of shells,
materials and loading conditions will be treated. The survey is limited to isotropic metallic shells
of revolution under quasi-static loading. Thus, stiffened posite shells are excluded.
Other limitations like shell geometries, which are not treated here, are mentioned in Sections 4
and 6.
The aim of the paper is to give an overview of basic concepts, and different aspects of buckling
and postbuckling behaviour with a focus on thin-walled shells. By a systematic description of
basic behaviour in the different load–deformation stages, better understanding of these very
complex problems should be reached.
