The effect of high loads on fatigue

Part of the IUTAM Symposia book series (IUTAM)


At first sight, it might be thought that occasional high loads would have little influence on fatigue, so long as the damage as indicated by the cumulative damage rule was small. This supposition is supported by results of tests made at the Aluminium Laboratories [1] on plain aluminium alloy specimens, when a single initial stretch in axial tension slightly reduced the fatigue strength in rotating bending, the maximum reduction being 12%, see table 1.
