“…7 shows that the predictions of the biaxiality effects in mesoscopic and macroscopic scales are very similar for the three considered criteria. These trends are also found in the experimental studies in the literature [25,26]. Fig.…”

Multiaxial high cycle fatigue modeling of materials is an issue that concerns many industrial domains (automotive, aerospace, nuclear, etc.) and in which many progress still remains to be achieved. Several approaches exist in the literature: invariants, energy, integral and critical plane approaches all of them having their advantages and drawbacks. These different formulations are usually based on mechanical quantities at the micro or mesoscales using localization schemes and strong assumptions to propose simple analytical forms. This study aims to revisit these formulations using a numerical approach based on crystal plasticity modeling coupled with explicit description of microstructure (morphology and texture) and proposes a statistical procedure for the analyses of numerical results in the HCF context. This work has three steps: First, 2.5D periodic digital microstructures based on a random grain sizes distribution are generated. Second, multiaxial cyclic loading conditions corresponding to the fatigue strength at 106 cycles are applied to these microstructures. Third, the mesoscopic Fatigue Indicator Parameters (FIPs), formulated from the different criteria existing in the literature, are identified using the finite element calculations of the mechanical fields. These mesoscopic FIP show the limits of the original criteria when it comes to applying them at the grain scale. A statistical method based on extreme value probability is used to redefine the thresholds of these criteria. These new thresholds contain the sensitivity of the HCF behavior to microstructure attributes. Finally, the biaxiality and phase shift effects are discussed at the grain scale and the loading paths of some critical grains are analyzed.

“…The endurance limit is dependent on the stress distribution in the mechanical part. Furthermore, in order to be in correct agreement with experiments, any high cycle multiaxial fatigue criterion has to be phase independent in combined plane bending and torsion (Papadopoulos, 1994) as shown by the experimental data of Simbtirger (1975) and Froustey and Lasserre (1989). According to the work of Simbtirger, however, the endurance limit seems to be phase dependent in biaxial traction (combined traction and internal/external pressure on thin walled tube).…”

“…The materials are: a 30NCD16 quenched and tempered steel (Froustey and Lasserre, 1989), a XC1 8 annealed steel , a 35CD4 quenched and tempered steel and a spheroidal graphite cast iron (AFNOR standard close to FGS800-2) (Bennebach, 1993) and (Palin-Luc, 1996). Their mechanical characteristics are given in Table I.…”

“…Due to the lack of other studies and limited number of experimental data, the suitability of the model to estimate the fatigue life of non-proportional loads with a non-zero mean value cannot be definitively determined. Only for one of the materials (steel 30NCD16), experimental studies for non-proportional loads of a non-zero mean value of stress (Froustey and Lasserre, 1989) were carried out. Unfortunately, this material is not sensitive to the mean shear stress.…”

This paper proposes a model for estimating fatigue life under multiaxial stress states, based on critical plane concepts, taking into account the effect of mean shear stress. The fatigue life test results calculated on the basis of the proposed model are compared to the experimental ones related to 2017A-T4 and 6082-T6 aluminium alloy, S355J0 alloy steel under constant-amplitude bending, torsion and proportional combinations of bending and torsion; Ti-6Al-4V alloy under tension-compression, torsion and combination tension-compression -torsion.
