STRENGTH AND ECONOMIC COMPARISON OF AUTOFRETTAGED VERSUS JACKETED PRESSURE VESSEL CONSTRUCTION

Abstract

The theoretical elastic strength of autofrettaged and jacketed thick- wall cylinders is presented in the form of equations and graphs. The mechanism by which both processes increase the elastic strength of a thick-wall cylinder is discussed and illustrated graphically. The advantages of a combination of jacketing and autofrettage for very thick-wall, pressure vessel applications are discussed and illustrated by a specific example. The economic advantages of autofrettage over jacketing are presented by a cost analysis of two specific examples, namely the 175mm Gun, T256 and the 155mm Howitzer T255.
