Description
Summary:This paper presents a global approach in order to predict the high-cycle fatigue (HCF) limit of turned parts. The multi-axial fatigue criteria of both Crossland and Dang Van are adapted for the case of machined parts. Thereby, the machined surface conditions which are residual stresses, superficial damage, and hardening, are taken into account in the both criteria. The suggested approach is conducted for turned AISI 316L stainless steel for various machining parameters. Otherwise, three types of cyclic loading, which are traction, torsion, and combined traction-torsion loadings, are applied onto the machined surface so as to investigate their effects on the HCF performance. The applicability of the used fatigue criteria and their efficiency in the prediction of the HCF indicator are discussed. A critical assessment of the beneficial or unbeneficial effects of each surface condition on the fatigue strength is investigated. The obtained results are physically consistent and are in good concordance with the available experimental investigations.
