    • A mechanistic approach to the Kitagawa-Takahashi diagram using a multiaxial probabilistic framework 
      Article dans une revue avec comité de lecture
      ccPESSARD, Etienne; ccBELLETT, Daniel; ccMOREL, Franck; ccKOUTIRI, Imade (Elsevier, 2013)
      The aim of this paper is to propose a flexible multiaxial modelling framework that is capable of combining two fatigue damage mechanisms so as to continuously describe the Kitagawa-Takahashi diagram. It is proposed that ...
    • Constitutive Modelling of AZ31B-O Magnesium Alloy for Cryogenic Machining 
      Communication avec acte
      GIRAUD, Eliane; ROSSI, Frederic; ccGERMAIN, Guénaël; MARTINS DO OUTEIRO, Jose Carlos (Elsevier, 2013)
      The success of a FE model for metal cutting process is strongly dependent on the accurate characterization of the workpiece material, under similar conditions as those found in metal cutting. In this paper, dynamic shear ...
    • Nonlinear dynamics of a rotating shaft with a breathing crack 
      Article dans une revue avec comité de lecture
      NGUYEN, Quoc Son; ccEL AREM, Saber (Springer Berlin Heidelberg, 2012)
      In this paper, the effects of a breathing crack on the vibratory characteris- tics of a rotating shaft are investigated. A new, simple and robust model composed of two rigid bars connected with a nonlinear flexural spring ...
    • Microstructural heterogeneities and fatigue anisotropy 
      Article dans une revue avec comité de lecture
      VERDU, Catherine; FLACELIERE, Laurent; BAUDRY, Gilles; ccMOREL, Franck; ccPESSARD, Etienne (Elsevier, 2011)
      In this study, various experimental methods are employed to determine the anisotropic fatigue behavior of a 25MnCrSiVB6 forged steel (Metasco MC). This material has a bainitic microstructure and contains many elongated ...
    • The Effect of microstructural heterogeneities on the fatigue behaviour of 22MnB5 sheet steel 
      Communication avec acte
      ABRIVARD, Benjamin; ccPESSARD, Etienne; ccMOREL, Franck; DELHAYE, Philippe; GERIN, Benjamin (V. Aubin, S. Courtin, A. Koster, 2013)
      This work deals with the effect of heat treatment on the fatigue strength of a rear axial beam and aims to propose a methodology suitable and reliable for fatigue design. The rear axial beam is made of sheet metal (22MnB5); ...
    • Reliability Estimation by ALT when no Analytical Model Holds 
      Article dans une revue avec comité de lecture
      LANTIERI, Pascal; GUERIN, Fabrice; HAMBLIA, Ridha (Wiley, 2010)
      This paper presents an accelerated life testing method applicable to devices or systems when no analytical relationship with respect to the stress level can be defined. If a numerical approach remains possible, the numerical ...
    • Modelling the role of non metallic inclusions on the anisotropic fatigue behaviour of forged steel 
      Article dans une revue avec comité de lecture
      ccPESSARD, Etienne; ccMOREL, Franck; MOREL, Anne; ccBELLETT, 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 ...
