    • Modeling laser drilling in percussion regime using constraint natural element method 
      Article dans une revue avec comité de lecture
      ILLOUL, Lounès; ccLORONG, Philippe; ccRANC, Nicolas; ccSCHNEIDER, Matthieu; ccFAVIER, Véronique; ccGIRARDOT, Jeremie (Springer Verlag, 2017)
      The laser drilling process is the main process used in machining procedures on aeronautic engines, especially in the cooling parts. The industrial problematic is to reduce geometrical deviations of the holes and defects ...
    • Kinetic analysis of polydicyclopentadiene oxidation 
      Article dans une revue avec comité de lecture
      DEFAUCHY, Virginie; LE GAC, Pierre Yves; GUINAULT, Alain; VERDU, Jacques; RECHER, Gilles; DROZDZAK, Renata; ccRICHAUD, Emmanuel (Elsevier, 2017)
      The in situ thermal oxidation of thin unstabilized polydicyclopentadiene was studied by TGA to monitor mass gain, and DSC to characterize hydroperoxides concentration. Results were discussed using kinetic analysis, which ...
    • Modélisation polycristalline du comportement d’un Alliage `a M´emoire de Forme (AMF) de type Ni-Ti sous sollicitations multiaxiales 
      Communication avec acte
      MAYNADIER, Anne; LAVERNHE-TAILLARD, Karine; HUBERT, Olivier; ccDEPRIESTER, Dorian (AFM, Maison de la Mécanique, 39/41 rue Louis Blanc, 92400 Courbevoie, France (FR), 2011)
      Les propriétés des AMF sont dues à une transformation de phase solide solide réversible induite par la contrainte ou la température. Pour les AMF de type Ni49,75%at-Ti, c’est une transformation isochore qui, d’une phase ...
    • Thermo-mechanical description of phase transformation in Ni-Ti Shape Memory Alloy 
      Communication avec acte
      MAYNADIER, Anne; LAVERNHE-TAILLARD, Karine; HUBERT, Olivier; ccDEPRIESTER, Dorian (Elsevier, 2011)
      The pseudo-elasticity of Shape Memory Alloys is due to a change in volumetric fraction between the high temperature phase (Austenite) and the low temperature phase (Martensite) under a mechanical loading. When a tensile ...
    • Fatigue Modelling for Gas Nitriding 
      Article dans une revue avec comité de lecture
      WEIL, Hadrien; ccJÉGOU, Sébastien; ccBARRALLIER, Laurent; COURLEUX, Alice; BECK, Guillaume (Università di Cassino, 2016)
      The present study aims to develop an algorithm able to predict the fatigue lifetime of nitrided steels. Linear multi-axial fatigue criteria are used to take into account the gradients of mechanical properties provided by ...
    • Modified WIC test : an efficient and effective tool for evaluating pipeline girth weldability 
      Article dans une revue avec comité de lecture
      KURJI, Rahim; GRIGGS, J.; GHOMASHCHI, R.; ccCONIGLIO, Nicolas (Maney Publishing, 2017)
      The Welding Institute of Canada (WIC) test is a simple and standardised weldability test for hydrogen assisted cold cracking that was developed in the 80s. It has been extensively utilised by the industry to qualify safe ...
    • A method to determine composite material residual tensile strength in the fibre direction as a function of the matrix damage state after fatigue loading 
      Article dans une revue avec comité de lecture
      CAOUS, Damien; ccBOIS, Christophe; ccWAHL, Jean-Christophe; ccPALIN-LUC, Thierry; VALETTTE, Julien (Elsevier, 2017)
      The phenomenon of residual strength in composite laminates after fatigue loading has been studied for decades but is generally expressed as a function of the number of cycles applied to the specimens. henomenological laws ...
