INVESTIGATION OF THERMALSTRESS-FATIGUE BEHAVIOR OF STAINLESS STEEL. THE EFFECTS OF GAGE LENGTH AND SPECIMEN CONFIGURATION ON THERMAL-STRESS-FATIGUE TEST RESULTS
The importance of the experimental method to thermalstress-fatigue test results is clarified. It is shown that a significant increase in apparent fatigue life can be obtained by measuring maximum strain per cycle instead of an average strain. Extrapoiation curves are given to convert the litter into the formed. A varying-cross-section specimen of zero'' gage length is shown to allow measurement of true, maximum strain. (auth)
