A Reliability-based Approach to Assess Fatigue Behaviour Based onSmall Incomplete Data Sets

摘要：

This paper outlines a new technique to address the paucity of data in determining fatiguelife and performance based on reliability concepts.Two new randomized models are presented forestimating the safe life and pS-N curve,by using the standard procedure for statistical analysis anddealing with small sample numbers of incomplete data.The confidence level formulations for the safeand p-S-N curve are also given.The concepts are then applied for the determination of the safe lifeand p-S-N curve.Two sets of fatigue tests for the safe life and p-S-N curve are conducted to validatethe presented method,demonstrating the practical use of the proposed technique.
