Numerical Solution to an Autofrettaged Tube with Constraining Walls and End Closures

Abstract

This report presents a numerical study of a container autofrettage process. This process uses internal hydraulic pressure to expand the tube, restraining containers to control the amount of tube expansion and the press force to hold the end closures. The incremental finite-difference approach developed recently by the author is extended to obtain numerical results. The effects of restraining walls and the press force on the displacements and stresses are discussed.
