A Specialized Toroidal Pressure Vessel 630410

A method is developed for determining the meridional contours of a toroidal shell which will produce no hoop stress resultants in the curved portion of the shell when subjected to internal pressure. The meridional membrane force will remain tensile. The resulting specialized toroidal pressure vessel design may eliminate the possibility of buckling failures found to be of critical concern in many other types of noncircular tori. Methods for finding the internal volume and surface area of such a pressure vessel are also presented.
