Abstract

In the present work, the effect of thermal aging on ratcheting behaviors of three pressurized elbow pipes after different thermal aging periods was experimentally studied under constant internal pressure and reversed in-plane bending. The elbow pipes were thermal aged for 1000 h and 2000 h at the same aging temperature of 500 centigrade degrees. It is indicated that thermal aging period has a significant effect on elbow pipe's ratcheting deformation. Chen-Jiao-Kim (CJK) kinematic hardening model was employed to evaluate the ratcheting behaviors of pressured elbow pipes affected by thermal aging.
