Rolling contact fatigue is a unique mode of that components under cyclic loading experience. In this work, the impact induction hardening residual stresses in rolling lifetime investigated experimentally and numerically using Dang Van multiaxial criterion. Various stress fields from are simulated finite element method mapped into classical mono-contact model. The hardened on component has been ...

This paper studies the multiaxial fatigue behaviour of maraging steel samples produced by selective laser melting. Hollow cylindrical specimens with transverse circular holes are subjected to different in-phase bending-torsion loading scenarios. Fatigue crack initiation sites and angles predicted from first principal stress field. lifetime is computed using a straightforward approach, based on ...

A specific design approach is formulated to notched components of additively manufactured AISI 316L against constant/variable amplitude multiaxial fatigue loading. The accuracy the proposed checked experimental results generated by testing, under biaxial loading, plain/notched cylindrical specimens 3D-printed 316L. Specific trials were run investigate also effect out-of-phase angles equal 90° a...
