Abstract
This paper deals with the buckling of a shallow spherical cap subjected to uniform edge moment and a clamped deep spherical shell under uniform pressure. The first problem is formulated in integral equations which are solved by an iterative procedure. The buckling moments are determined for a wide range of the shell geometrical parameter. The second problem is based on the concept that the highly deformed region around the apex is treated as a shallow spherical cap elastically supported by the rest of the shell. The stability of a thin sphere is treated as a special case. The results obtained in both problems are compared with existing solutions.
