Ratcheting behavior of 90 elbow piping subject to internal pressure 20 MPa and reversed bending 20 kN was investigated using experimental method. The maximum ratcheting strain was found in the circumferential direction of intrados. Ratcheting strain at flanks was also very large. Moreover, the effect of temperature on ratcheting strain of 90 elbow piping was studied through finite element analysis, and the results were compared with room condition (25). The results revealed that ratcheting strain of 90 elbow piping increased with increasing temperature. Ratcheting boundary of 90 elbow piping was determined by Chaboche model combined with C-TDF method. The results revealed that there was no relationship between the dimensionless form of ratcheting boundary and temperature.
