Fatigue life prediction of an autofrettaged thick-walled pressure vessel subjected to a pulsating high internal pressure was made to prevent catastrophic failure of the pressure vessel. Elastic-plastic stress analysis of the autofrettaged pressure vessel was performed by using finite element method, and low-cycle fatigue test was performed to determine fatigue properties of the pressure vessel steel. Fatigue life of the pressure vessel was predicted using the finite element stresses and fatigue damage parameter, resulting in 24,521 cycles. Simulation fatigue test in the laboratory was performed in order to verify the predicted fatigue life of the pressure vessel using the C-type simulation test specimen. Predicted fatigue life and simulated fatigue life were in good agreement.
