    • Crosslink Density Changes during the Hydrolysis of Tridimensional Polyesters 
      Article dans une revue avec comité de lecture
      GILORMINI, Pierre; COQUILLAT, Marie; VERDU, Jacques; ccRICHAUD, Emmanuel (Wiley-VCH Verlag, 2014)
      The hydrolysis of almost ideal networks based on macrodiols of average molar mass about 2 kg mol 1, with L¼18 ester groups per chain is studied. Tensile testing is used to evaluate the crosslink density through the statistical ...
    • Generation and characterization of T40/A5754 interfaces with lasersPatrice 
      Article dans une revue avec comité de lecture
      PEYRE, Patrice; BERTHE, Laurent; POUZET, Sébastien; SALLAMAND, Pierre; TOMASHCHUK, Iryna; ccDAL, Morgan (Elsevier, 2014)
      Laser-induced reactive wetting and brazing of T40 titanium with A5754 aluminum alloy with 1.5 mm thickness was carried out in lap-joint configuration, with or without the use of Al5Si filler wire. A 2.4 mm diameter laser ...
    • Thermomechanical and hygroelastic properties of an epoxy system under humid and cold-warm cycling conditions 
      Article dans une revue avec comité de lecture
      EL YAGOUBI, Jalal; LUBINEAU, Gilles; SAGHIR, Shahid; VERDU, Jacques; ASKARI, Abe (Elsevier, 2014)
      In this paper, we study the hygrothermal aging of an anhydride-cured epoxy under temperature and hygrometry conditions simulating those experienced by an aircraft in wet tropical or subtropical regions. Gravimetric and ...
    • Towards gigantic RVE sizes for 3D stochastic fibrous networks 
      Article dans une revue avec comité de lecture
      DIRRENBERGER, Justin; FOREST, Samuel; JEULIN, Dominique (Elsevier, 2014)
      The size of representative volume element (RVE) for 3D stochastic fibrous media is investigated. A statistical RVE size determination method is applied to a specific model of random microstructure: Poisson fibers. The ...
    • A study of composite material damage induced by laser shock waves 
      Article dans une revue avec comité de lecture
      ESCAULT, Romain; BOUSTIE, Michel; TOUCHARD, Fabienne; PONS, Frédéric; BERTHE, Laurent; CHOCINSKI-ARNAULT, Laurence; EHRHART, Bastien; BOCKENHEIMER, Clemens (Elsevier, 2013)
      A laser shock wave technique has been used to study the damage tolerance of T800/M21 CFRP (Carbon Fiber Reinforced Polymer) composite material with different lay_ups. Different levels of damage have been created according ...
    • Thermal oxidation kinetics of additive free polyamide 6-6 
      Article dans une revue avec comité de lecture
      EL MAZRY, Chaker; BEN HASSINE, Mouna; CORREC, Olivier; ccCOLIN, Xavier (Elsevier, 2013)
      Thermal aging of an additive free PA 6-6 has been elucidated at 90, 100, 120, 140, 150 and 160 C in airventiled ovens by Fourier transform infrared spectrophotometry, viscosimetry in molten state and uniaxial tensile ...
    • Vibroacoustics of the piano soundboard : (Non)linearity and modal properties in the low- and mid-frequency ranges 
      Article dans une revue avec comité de lecture
      EGE, Kerem; BOUTILLON, Xavier; ccRÉBILLAT, Marc (Elsevier, 2013)
      The piano soundboard transforms the string vibration into sound and therefore, its vibrations are of primary importance for the sound characteristics of the instrument. An original vibro-acoustical method is presented to ...
