Abstract

Homologous temperature low cycle fatigue data on type 316 austenitic stainless steel have been collected and analyzed using fracture mechanics approach. Average fatigue curves between 10and 106 cycles have been produced over the temperature rang Room Temperature to 766°C (following homologous temperature range of 0.0 165,0.05, 0.1, 0.15, 0.2, 0.25, 0.3, 0.35, 44, 0,42 and 0.50). A modified approach for deriving predicted fatigue life curves has been developed in the present work. The developed approach successfully modeled the fatigue endurance in terms of total strain range and a family of temperature dependent fatigue curves has been derived. The data curves have been translated into design curves. Furthermore, the derived fatigue curves are then compared with the available fatigue curves.
