Abstract

Detailed results of stress-controlled fatigue tests with tensile mean stress on ASTM A-516 Gr. 70 steel are presented. By using different preloading procedures, the ratcheting effect on the fatigue life of materials was separated from the mean stress effect. A previously proposed energy-based life prediction criterion is extended to include the effects of both mean stress and ratcheting. A comparison between the theoretical prediction with the present test results is found to be quite satisfactory.
