    • 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, ...
    • Method to obtain hybrid rapid tools with elementary component assembly 
      Article dans une revue avec comité de lecture
      MOGNOL, Pascal; HASCOET, Jean-Yves; ccRIVETTE, Mickaël (Emerald, 2013)
      Purpose – The purpose of this paper is to propose a method to obtain hybrid rapid tools with elementary component assembly. Design/methodology/approach – The authors' method proposes a functional representational model, ...
    • 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 ...
