✦ Synopsis

A new theoretical model for reverse yielding in a high strength steel is used to obtain residual stresses in a closed-end thick-walled cylinder subjected to high internal pressure. The numerical results of residual hoop stresses are also obtained by using the isotropic and kinematical hardening models. A comparison of different models in the theoretical prediction of residual stress is given. The new results indicate that the influence of the Bauschinger and hardening effects on the residual stresses are more significant for cases involving larger wall ratio and higher internal pressure.
