WebS1 is the fatigue strength coefficient. Nc1 is cyclic limit of endurance. The S-N approach is based on elastic cyclic loading, inferring that the S-N curve should be confined, on the life axis, to numbers greater than 1000 cycles. This ensures that no significant plasticity is occurring. This is commonly referred to as high-cycle fatigue. WebThe fatigue life prediction approach they used is called the extrapolated radial stress (ERS) approach, which is a modification of regular structure stress approach developed by Radaj and Soegiharto.
