Computer automation process for the design of single and multiple walled high pressure vessels

The purpose of this thesis was to develop a user friendly software package to speed the calculation of the stress states of high pressure multiple walled vessels. A residual stress pattern is created in these vessels using autofrettage and the shrinkfitting processes. This residual stress pattern improves the vessel's ability to perform at high pressures. The solution method considers the effects of strain hardening and the Bauschinger effect. The software was implanted to perform on a Macintosh platform. The Macintosh was chosen for the software development because, in the author's opinion, Macintosh's intuitive user interface will allow the widest use of the software. This software package allows the criteria of the problem to be quickly changed so that the user may produce a design for a high pressure vessel in an efficient manner. The software also generates stress graphs, and a complete report for each design providing the user with complete documentation of the design generated.
