    • Yb–YAG laser offset welding of AA5754 and T40 butt joint 
      Article dans une revue avec comité de lecture
      CASALINO, Giuseppe; MORTELLO, Michelangelo; PEYRE, Patrice (Elsevier, 2015)
      In this work, a 5754 Al alloy and T40 were joined in butt configuration by focusing a fiber laser onto the titanium side, close to the weld centerline (offset). The keyhole was made entirely of titanium, and the fusion of ...
    • Micromechanical modelling of twinning-induced plasticity steels 
      Article dans une revue avec comité de lecture
      BARBIER, D; ccFAVIER, Véronique (Elsevier, 2012)
      The paper discusses a number of issues related to the development of a micromechanical polycrystalline model for twinning-induced plasticity steels: twinning features that have to be incorporated, identification procedure, ...
    • Role of machining defects and residual stress on the AISI 304 fatigue crack nucleation 
      Article dans une revue avec comité de lecture
      YAHYAOUI, Houda; BEN MOUSSA, Naoufel; SIDHOM, H; BEN FREDJ, N; ccBRAHAM, Chedly (Wiley-Blackwell, 2015)
      Machining defects as rebuilt material and dislodgement were often induced by cutting of difficult to machining AISI 304 stainless steel. Their density increases with a decreasing of cutting speed. The effect of these defects ...
    • Fuel cell rejuvenation of hygrothermally aged Nafion 
      Article dans une revue avec comité de lecture
      COLLETTE, Floraine; THOMINETTE, Francette; ESCRIBANO, Sylvie; RAVACHOL, Angèle; MORIN, Arnaud; GEBEL, Gérard (Elsevier, 2012)
      Nafion ® membranes stored for long periods at 80 °C under elevated relative humidity up to 95%RH exhibit large modifications of their properties attributed to the sulfonic acid end-group condensation into sulfonic anhydrides. ...
    • Temperature measurement of laser heated metals in highly oxidizing environment using 2D single-band and spectral pyrometry 
      Article dans une revue avec comité de lecture
      MULLER, Maryse; FABBRO, Rémy; EL-RABII, Hazem; HIRANO, Koji (Laser Institute of America, 2012)
      Calibration and validation of two temperature measurement techniques both using optical pyrometry, usable in the framework of the study of the heated metals in highly oxidizing environments and more generally during laser ...
    • A multi-sine sweep method for the characterization of weak non-linearities ; plant noise and variability estimation. 
      Communication avec acte
      GALLO, Maxime; EGE, Kerem; ANTONI, Jérôme; ccRÉBILLAT, Marc (2015)
      Weak non-linearities in vibrating structures can be characterized by a signal-model approach based on cascade of Hammerstein models. The experiment consists in exciting a device with a sine sweep at different levels, in ...
    • OSCAR Statement of Methods 
      Article dans une revue avec comité de lecture
      MASSAT, Jean-Pierre; BALMES, Etienne; BIANCHI, Jean-Philippe; VAN KALSBEEK, Guido (Taylor & Francis, 2015)
      OSCAR (Outil de Simulation du CAptage pour la Reconnaissance des défauts) is the pantograph–catenary dynamic software developed by Société Nationale des Chemins de fer Français (SNCF) since 2004. A three-dimensional finite ...
