SAE CUMULATIVE FATIGUE DAMAGE TEST PROGRAM
Although not exhaustive, this test program has produced a set of fatigue data of sufficient generality that methods of fatigue life prediction (both crack initiation and propagation) and laboratory simulation can be reasonably evaluated. The test data also provides other insights: Generally, the stronger steel had the longer crack initiation life and crack propagation life at all load levels for all histories. The inverse slope of the variable amplitude life lines varied from -3.8 to -7.25. Compressive mean loads resulted in less steep slopes.
