    • 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 ...
    • Une méthodologie de conception pour la fabrication additive 
      Communication sans acte
      RODRIGUE, Hugo; CALATORU, Victor; ccRICHIR, Simon; ccRIVETTE, Mickaël (Congrès International de Génie Industriel, 2011)
      Résumé - Les méthodologies de Design for Assembly et de Design for Manufacturing visent à rendre les produits plus faciles à fabriquer et à assembler en se basant sur les caractéristiques des procédés actuels de fabrication, ...
    • The anisotropic fatigue behavior of forged steel 
      Article dans une revue avec comité de lecture
      MOREL, Anne; ccMOREL, Franck; ccPESSARD, Etienne (Wiley-VCH Verlag, 2009)
      This work deals with the anisotropic fatigue behaviour of the Bainitic Steel Metasco®MC and aims at improving the fatigue criteria used for the design of forged components (suspension arm). This material contains elongated ...
    • Micromechanical modeling if the interactions between the microstructure and the dissipative deformation mechanisms in steels under cyclic loading 
      Article dans une revue avec comité de lecture
      ccMAREAU, Charles; ccFAVIER, Véronique; WEBER, Bastien; GALTIER, André; BERVEILLER, Marcel (Elsevier, 2012)
      A micromechanical model is proposed to describe the interactions between the microstructure and the dissipative deformation mechanisms in ferritic steels under cyclic loading. The model aims at optimizing the microstructure ...
    • 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 ...
    • Comparison between incremental deformation theory and flow rule to simulate sheet-metal forming processes 
      Article dans une revue avec comité de lecture
      ROBERT, Camille; DELAMEZIERE, Arnaud; DAL SANTO, Philippe; BATOZ, Jean-Louis (Elsevier, 2012)
      Numerical simulation of the deep drawing process for the manufacture of aeronautical or automotive components should predict with good accuracy the behaviour during the forming operation, taking into account, the material ...
