Abstract This study examines the previous experimental results of ratcheting behavior of elbow pipe made of Z2CN18.10 austenitic stainless steel subjected to constant internal pressure and reversed in-plane bending by Chen-Jiao-Kim (CJK) kinematic hardening model as a user subroutine of ANSYS. A set of more precise CJK model parameters were determined. Based on the new model parameters, the evolutions of ratcheting behavior of pressurized elbow pipe were made under two sets of different loading paths. The paths consist of the alternation of internal pressure and bending moment, and bending-torsion combination under constant internal pressure. The preliminary results claim that different loading paths have a significant effect on ratcheting behavior of pressurized elbow pipe.
