Life Prediction of Thermal-Mechanical Fatigue Using Strainrange Partitioning

Source

This paper describes the features of the method of strainrange partitioning that make it applicable to the life prediction of thermal-mechanical strain-cycling fatigue. An in-phase (230 to 760°C) test on Type 316 stainless steel is analyzed as an illustrative example. The method utilizes the recently proposed step-stress procedure of experimental partitioning, the interaction damage rule, and the life relationships determined at an isothermal temperature of 705°C. Implications of the present study are discussed relative to the general thermal fatigue problem.
