Fatigue is a complex phenomenon that is influenced by a number of factors (e.g. surface finish). It is therefore important to carefully analyze components subjected to fluctuating loads so that the desired reliability can be built into these components and over-designed or under-designed components can be avoided. Accordingly, predicting fatigue life has been one of the most important problems in design engineering for reliability and quality. This session aims to bring together scientists and researchers from both experimental and modelling field of fatigue research.
