A multiaxial criterion for high cycle fatigue based on invariants of macroscopic stress tensor is proposed. The presence of J 2,mean allows capturing accurately effects of phase shift and frequency on fatigue limit of material under multiaxial loading. Prediction capacity of the proposed criterion i
This paper summarises an attempt to propose a novel stress invariant based approach suitable for estimating fatigue damage in the presence of complex multiaxial fatigue loadings. In more detail, according to the devised method, fatigue damage is evaluated by studying the components of the deviator p
Artificial spherical defects (400 lm) are introduced at the surface of C35 steel fatigue samples. Fatigue tests are conducted under tension and torsion with different mean stress levels in order to determine the fatigue limit. Experimental results show that the effect of mean stress under both torsi
