Abstract : Experiments have been performed to investigate the strain-controlled low cyclic fatigue (LCF) behavior and cyclic behavior of ratcheting of annealed austenitic stainless steel. While LCF experiments have been carried out under completely reversed straining conditions at a range between +/–0.375 and +/–1.00% of five strain amplitudes, experiments have been performed to observe the mean stress effect on the cyclic behavior of ratcheting of the solution annealed austenitic stainless steel (AISI 304) for 1000 cycles keeping the stress amplitude constant. The present study also looks into the cyclic ratcheting effect on the LCF behavior of the steel. Results of LCF and ratcheting tests have been analyzed to observe the LCF resistance of the investigated steel and to understand the response of the steel to the interaction of ratcheting fatigue.
