This paper describes the effect of nonproportional loading on low cycle fatigue lives for type 304 and 316FR stainless steels at room temperature an 923K, respectively. Strain controlled tension-torsion low cycle fatigue tests were carried out using hollow cylinder specimens under two proportional and thirteen nonproportional strain paths at a strain rate of 0.1%/s. Nonproportional straining significantly reduced fatigue lives of the steels at room temperature and 923K. Reduction of the live due to the nonproportional straining reached about 10% compared with the proportional lives in specific strain paths. Nonproportional strain range proposed, delta(epsilon(NP)), successfully correlated the nonproportional fatigue lives but the equivalent strain defined in ASME code case gave a significantly unconservative prediction for the steels.
