Abstract
By far the commonest geometry used for high pressure vessels is the thick-walled cylinder. In such a vessel the bore material is more highly stressed than that in the outer layers which thus contributes little to resisting the internal pressure. This paper presents a review of the various methods which have been proposed for achieving better utilization of the peripheral material.
The pressure and thermal stresses in a simple elastic cylinder are examined and the analysis of a partially plastic cylinder discussed with autofrettage in mind. A section is included on compound cylinder design including carbide liners and wire and strip winding. A new technique involving the use of low modulus liners is suggested. Sectorial vessel design and cascading of vessels is also considered. The various techniques are compared and their practical difficulties and limitations discussed.
