ELASTIC-PLASTIC ANALYSIS OF THE COLLAPSE OF UNIFORMLY COMPRESSED CIRCULAR CYLINDRICAL SHELLS,
Abstract
A new geometric form is proposed as a large-displacement buckling pattern of a circular cylindrical shell of finite length simply supported at the ends and subjected to axial compressive load. Exact expressions are derived for displacements and membrane strains. They show that the new pattern is almost entirely free of membrane strain. During buckling plastic yield hinges are assumed to develop which form ridges separating the mostly flat buckled surfaces. The buckling load and the postbuckling load are calculated from the energy balance and from a compatibility condition of the displacements of test specimen and elastic testing machine. (Author)
