Description
Design fatigue curve is used in low-cycle fatigue design widely. The required basic strain-controlled data for SA372-J70 steel were obtained in room temperature condition. The 'cyclic' stress-strain properties of the material were also obtained and were found to differ quite significantly from conventional properties. The monotonically increasing strain accompanies the cyclic strain. The effects of such a gradually accumulating increment of strain were investigated and were found to be adequately covered by the adjustment for maximum mean stress. Design curve were constructed from the mean failure curve by applying safety factors to cover the effects of size, environment, surface finish and scatter of data. Compared the design fatigue curve with the curve in ASME Code Sec. VIII Division 2, the results show it is suitable and safe to adopt ASME design fatigue curve for homemade SA372-J70 steel. (authors)
