Notes:
Fatigue reliability theory has recently verified that the sampling size related effect shouldbe taken into account by confidence (C). However, most of the historic probabilistic S-N curves aregiven to only consider the scattered regularity effect by survival probability (P). Therefore, areconstruction method of the historic curves is investigated to consider the sampling size effect. Aneffort is made on addressing the true production that the sampling size is less than 20 for materialspecimens and 10 for structural component specimens. A Monte Carlo simulation approach is firstestablished to reconstruct the test S-N data. And then, the P-C-S-N curves are reconstructed with ageneral maximum likelihood principle. The practice for 40Cr steel has clearly indicated that, beyondall doubt, the reconstructed curves has overcome the shortages of the historic data
