Evaluation of the -S/N- Fatigue Life Gage Under Constant and Variable Amplitude Loading.
Abstract
An experimental program was conducted to evaluate the -S/N- Fatigue Life Gage and a number of gage installations was evaluated for constant and variable amplitude loading. The test results demonstrated that while there was a qualitative relation between gage resistance change and specimen life expended, a usable quantitative correlation was not attainable. Test results also proved that the fraction of specimen life to initial detectable crack was a better indicator of the time for retirement of a structure than was the fatigue life gage, although no estimate of the damage incurred can be obtained prior to crack detection.
