    • Simulation numérique du perçage laser par la méthode C-NEM 
      Communication avec acte
      ILLOUL, Lounès; BERTHE, Laurent; ccLORONG, Philippe; ccRANC, Nicolas; ccSCHNEIDER, Matthieu; ccFAVIER, Véronique; ccGIRARDOT, Jeremie (2012)
      Ces travaux présentent une alternative numérique au problème de simulation du procédé de perçage par laser. L’utilisation des éléments finis pour modéliser la propagation du trou au cours du temps montre des limites ...
    • Simulation of green wood milling with discrete element method 
      Communication avec acte
      PFEIFFER, Renaud; ccLORONG, Philippe; ccRANC, Nicolas (2015)
      During the primary transformation in wood industry, logs are faced with conical rough milling cutters commonly named slabber or canter heads. Chips produced consist of raw materials for pulp paper and particleboard industries. ...
    • Simulation of the laser drilling process with the Constraint Natural Element Method 
      Communication avec acte
      ILLOUL, Lounès; BERTHE, Laurent; ccLORONG, Philippe; ccRANC, Nicolas; ccSCHNEIDER, Matthieu; ccFAVIER, Véronique; ccGIRARDOT, Jeremie (2012)
      These works present a numerical alternative to the simulation of the laser drilling process. The use of the finite element method to modeling the hole creation during a laser pulse shows difficulties in front of a moving ...
    • An Approach to the Health Monitoring of the Fuel System of a Turbofan 
      Communication avec acte
      LAMOUREUX, Benjamin; MASSÉ, Jean-Rémi; ccMECHBAL, Nazih (IEEE, 2012)
      This paper focuses on the monitoring of the fuel system of a turbofan which is the core organ of an aircraft engine control system. The paper provides a method for real time on-board monitoring and on-ground diagnosis of ...
    • Direct experimental evidence of time-temperature superposition at finite strain for an amorphous polymer network 
      Article dans une revue avec comité de lecture
      DIANI, Julie; GILORMINI, Pierre; ARRIETA, Juan Sebastian (Elsevier, 2015)
      The time-temperature superposition property of an amorphous polymer acrylate network is characterized at infinitesimal strain by standard dynamic mechanical analysis tests. Comparison of the shift ...
    • Study of an Industrial FEM tool for line boring process of cylinder blocks 
      Communication avec acte
      TABIBIAN, Shadan; ccLORONG, Philippe (Trans Tech Publications, 2015)
      The aim of this study is to realize a simple simulation tool, in order to predict the form defect of cylinder block bore liners in the moment of rough boring process. In this study a simple static FEM model, based on the ...
    • Experimental characterization of the intragranular strain field in columnar ice during transient creep 
      Article dans une revue avec comité de lecture
      GRENNERAT, Fanny; MONTAGNAT, Maurine; CASTELNAU, Olivier; VACHER, Pierre; MOULINEC, Hervé; SUQUET, Pierre; DUVAL, P (Elsevier, 2012)
      A digital image correlation (DIC) technique has been adapted to polycrystalline ice specimens in order to characterize the development of strain heterogeneities at an intragranular scale during transient creep deformation ...
