    • 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 ...
    • Thermooxidative aging of polydicyclopentadiene in glassy state 
      Article dans une revue avec comité de lecture
      LE GAC, Pierre Yves; VERDU, Jacques; LE GAC, Pierre Yves; ccRICHAUD, Emmanuel (Elsevier, 2014)
      Thermal aging of thin films of unstabilized polydicyclopentadiene (pDCPD) at several temperatures ranging from 120 to 30 C was investigated by means of carbonyl build up by FTIR with ammonia derivatization, double bond ...
    • Co-oxidation kinetic model for the thermal oxidation of polyethylene-unsaturated substrate systems 
      Article dans une revue avec comité de lecture
      VERDU, Jacques; RYCHLÝ, Jozef; ccFAYOLLE, Bruno; ccRICHAUD, Emmanuel (Elsevier, 2013)
      The thermal oxidation of polyethylene (PE) impregnated by the methyl esters of unsaturated fatty acids (UFEs) was studied using chemiluminescence, and infra-red spectrophotometry. It was shown that the presence of UFEs ...
    • Benchmarking Signorini and exponential contact laws for an industrial train brake squeal application 
      Communication avec acte
      VERMOT DES ROCHES, Guillaume; BALMES, Etienne; CHIELLO, Olivier; LORANG, Xavier (2012)
      Contact representation of structure interactions for finite element models is nowadays of great interest in the industry. Two contact modellig strategies exist in the literature, either based on a perfect contact with no ...
    • Development of a laser shock adhesion test for the assessment of weak adhesive bonded CFRP structures 
      Article dans une revue avec comité de lecture
      EHRHART, Bastien; ECAULT, Romain; TOUCHARD, Fabienne; BOUSTIE, Michel; BERTHE, Laurent; BOCKENHEIMER, Clemens; VALESKE, Bernd (Elsevier, 2014)

    • Chain branching detection by Cole–Cole modeling of rheological properties changes during PET mechanical recycling 
      Article dans une revue avec comité de lecture
      NAIT-ALI, K.L.; BERGERET, A; FERRY, L; ccCOLIN, Xavier (Elsevier, 2012)
      The detection of branched chains in thermally degraded thermoplastic polymers is far from simple, especially at a low conversion ratio, mainly because of the low sensitivity of commonly used laboratory analytical techniques. ...
