A broad survey is made of the available theoretical and experimental investigations of buckling of thin-walled monocoque circular cylindrical shells subjected to uniform external pressure. A simple, approximate method of analysis for the buckling of such a shell is offered for the purpose of stress analysis. The loading with hydrostatic external pressure is considered as a special case of the interaction relation, and the method of analysis for this case is based on an approximate interaction relation derived from earlier theory. Available test data are presented in tabular form. Diagrams are included in which properly selected test data are evaluated. A diagramatic comparison of the suggested method of analysis and the test data shows a reasonably close agreement. Author
