    • Parameter identification of advanced plastic potentials and impact on plastic anisotropy prediction 
      Article dans une revue avec comité de lecture
      RABAHALLAH, Meziane; BOUVIER, Salima; BACROIX, Brigitte; BARLAT, Frédéric; CHUNG, Kwansoo; TEODOSIU, Cristian; ccBALAN, Tudor (Elsevier, 2009)
      In the work presented in this paper, several strain rate potentials are examined in order to analyze their ability to model the initial stress and strain anisotropy of several orthotropic sheet materials. Classical quadratic ...
    • Influence of material structure on deep hole machinability of Super High Strength Steels 
      Article dans une revue avec comité de lecture
      BOMONT-ARZUR, Anne; CONFENTE, Mario; BOMONT, Olivier; SCHNEIDER, Emmanuel; BOMONT-ARZUR, Anne; ccLESCALIER, Christophe (Inderscience, 2007)
      The gain of productivity in machining is generally sought through tools and/or cutting conditions optimization however an increase in productivity is achievable too through the workmaterial optimization. The metallurgical ...
    • Super High Strength Steel for automotive applications 
      Communication avec acte
      BOMONT-ARZUR, Anne; CONFENTE, Mario; SCHNEIDER, Emmanuel; BOMONT, Olivier; BOMONT-ARZUR, Anne; ccLESCALIER, Christophe (Technische Universität Darmstadt, 2008)
      Intensive weight savings and out-sizing programs are developed in automotive industry and lead to increase the mechanical properties of the material of the automotive parts. ArcelorMittal has developed specific steel grades ...
    • Elastic-plastic ductile damage model based on strain-rate plastic potential 
      Article dans une revue avec comité de lecture
      CAZACU, Oana; ccBALAN, Tudor (Elsevier, 2013)
      Modeling of ductile damage is generally done using analytical potentials, which are expressed in the stress space. In this paper, for the first time it is shown that strain rate potentials which are exact conjugate of the ...
    • Phenomenological model for phase transformation characteristics of textured shape memory alloys 
      Conférence invitée
      CHATZIATHANASIOU, Dimitris; CHEMISKY, Yves; CHATZIGEORGIOU, George; PATOOR, Etienne; ccMERAGHNI, Fodil (Ibrahim Karaman, Raymundo Arróyave and Eyad Masad/ Wiley, 2015)
      In the present study, a new transformation criterion that includes the effect of tension- compression asymmetry and texture-induced anisotropy is proposed and combined with a thermodynamical model to describe the ...
    • Micromechanical Fatigue Visco-Damage Model for Short Glass Fiber Reinforced Polyamide-66 
      Communication avec acte
      DESPRINGRE, Nicolas; CHEMISKY, Yves; ROBERT, Gilles; ccMERAGHNI, Fodil (Ibrahim Karaman, Raymundo Arróyave and Eyad Masad / Wiley, 2015)
      This work presents a micromechanical fatigue damage model developed for short glass fiber reinforced PA66. It has been developed to predict the high cycle fatigue behavior of PA66/GF30. The model is based on an extended ...
    • Investigation and modeling of the fatigue damage in natural fiber composites
