MOREL, Franck; PESSARD, Etienne (EDP Sciences, 2010)
L’objectif de cette étude est de proposer un critère de fatigue anisotrope pour le dimensionnement en fatigue de pièces industrielles forgées. Des résultats de différentes campagnes d’essais obtenus sur 3 nuances d’acier ... -

We propose a theoretical basis on the phenomenon of levitation of a sphere in a slightly conical tube. Using the results of our previous calculations on the effects of the hydrodynamic interactions on the Stokes force ...

Modelling the role of non metallic inclusions on the anisotropic fatigue behaviour of forged steel Article dans une revue avec comité de lecturePESSARD, Etienne; MOREL, Franck; ; BELLETT, Daniel (Elsevier, 2011)
Forged components are known to show high cyclic and monotonic mechanical properties. This is mainly due to a better compactness and a finer microstructure introduced by the forming process. However, this good mechanical ...

Fatigue phenomena, which appear generally below the yield stress, is the cause of more than 80 % of in-service mechanical failures. However, the optimization of the weight and cost when designing mechanical components or ...

Article dans une revue avec comité de lecture; ;MOREL, Franck (Elsevier, 2007)
The aim of this paper is to present new modelling dedicated to multiaxial high cycle fatigue (HCF), and applied to polycrystalline metals. The model presented is based on the experimental characterization of damage during ...

Article dans une revue avec comité de lectureMAREAU, Charles; ; MOREL, Franck (Elsevier, 2013)
To obtain robust estimations of the fatigue limit from energy-based fatigue criteria, constitutive laws must include a correct description of the energy balance when modeling the cyclic behavior. The present paper aims at ...

Communication avec acte; ;MOREL, Franck; SAINTIER, Nicolas; PALIN-LUC, Thierry (2013)
An analysis of high cycle fatigue behavior is done via the numerical simulation of polycrystalline aggregates. Different metallic materials with a FCC crystalline structure, but different cubic elastic coefficients, are ...
