Collapse Pressure for the Pressure Vessel Consisting of a Cylindrical Shell, a Toroidal Shell and a Rigid Circular Plate

Abstract

The collapse pressure for a pressure vessel which consists of a cylindrical shell, a toroidal shell and a rigid circular plate, is studied in this paper by means of the method of limit analysis. The results of analysis are summarized in a diagram and an approximate design formula. In order to study the practical significance of the theoretical collapse pressure of a pressure vessel, experiments are carried out, and it is found that agrecment exists between the theoretical and the experimental results. Furthermore the obtained theoretical results are compared with those of elastic analysis which was made by one of the authors and other, and almost same tendencies are found in both analysis.
