One of the design method for closing the end of a pressure cylinder is to screw down a screw plug on the threaded end of the cylinder. In the design of a pressure cylinder, it is very important to investigate stress and strain distribution in the threaded end of the cylinder which is subjected to internal pressure in the vessel. In this study, in order to clarify the behaviour of the threaded end of a pressure cylinder, the authors present a simple strength analysis method using the finite element method and the results calculated using it. The method proposed here makes it possible to analyze easily the stress and strain distributions in the threaded end of the pressure cylinder and to investigate speedily the effect of specifications such as cylinder thickness, plug length, screw thread size and initial clamping force.
