Abstract

High cycle fatigue properties of steels are usually characterized in the as-delivered state of the material. However, forming process, variable amplitude and accidental loading, called load history, could affect HCF properties. Given that investigating those history effect of fatigue properties by means of regular fatigue test would be very time consuming, self-heating measurements under cyclic loading were considered. Two load history effects were studied, a macroscopic plastic pre-strain and a cyclic pre-loading, by means of self-heating measurements under cyclic loading. All of the findings were used to propose a modification of a probabilistic two-scale model, which links self-heating measurements to HCF properties, given in the accompanying paper.
