Abstract

Previous results of the authors on austenitic stainless steel 316L [1,2] prompted similar tests on other materials. Another batch of this material was included in the testing, along with two mild steels and aluminium. The mechanical behaviour observed suggests that the interaction between low cycle fatigue (LCF) and high cycle fatigue (HCF) applied sequentially can result in a linear cumulative damage law. However, the results also show that an overall loss in fatigue life of the material is more likely to occur. Interestingly, LCF pre-straining can also lead to the extension of overall HCF life. Fatigue life was found to be dependent upon material composition, heat treatment and fatigue waveform.
