Stress and Deformation Analysis of Autofrettaged High Pressure Vessels.

Abstract

A method of stress and deformation analysis based on a new theoretical model is reported. The new model is a close representation of the actual loading/unloading behavior in a high strength steel. Bauschinger effect factor is treated as a function of overstain. The strain-hardening effect is taken into account with different parameters used for loading and unloading processes. The formulas for calculating stresses, strains, and displacements are given and new results of residual stresses in autofrettaged high pressure vessels are presented. (Author)
