    • Compatibility measure and penalized contact resolution for incompatible interfaces 
      Article dans une revue avec comité de lecture
      VERMOT DES ROCHES, Guillaume; BALMES, Etienne; BEN DHIA, Hachimi; LEMAIRE, Rémi; PASQUET, Thierry (Hermès / Paris : Lavoisier, 2010)
      Handling of large industrial mechanical assemblies implies structure interactions commonly modeled with contact formulations. In cases where component interfaces are discretized using non conforming meshes, classical contact ...
    • Potential fatigue strength improvement of AA 5083-H111 notched parts by wire brush hammering: Experimental analysis and numerical simulation 
      Article dans une revue avec comité de lecture
      SIDHOM, Naziha; BEN MOUSSA, Naoufel; JANEB, Sameh; SIDHOM, Habib; ccBRAHAM, Chedly (Elsevier, 2014)
      The effects of milling as machining process and a post-machining treatment by wire-brush hammering, on the near surface layer characteristics of AA 5083-H111 were investigated. Surface texture, work-hardening and residual ...
    • Oxidation induced changes in viscoelastic properties of a thermostable epoxy matrix 
      Article dans une revue avec comité de lecture
      MILLE, Marion; ccFAYOLLE, Bruno; ccCOLIN, Xavier; ccTEREKHINA, Svetlana (Wiley, 2013)
      The thermal ageing of a neat epoxy matrix has been studied at 200°C in air by three complementary analytical techniques: optical microscopy, mechanical spectrometry and nano-indentation. Thermal oxidation is restricted in ...
    • Observation of the shock wave propagation induced by a high-power laser irradiation into an epoxy material 
      Article dans une revue avec comité de lecture
      ESCAULT, Romain; BERTHE, Laurent; BOUSTIE, Michel; TOUCHARD, Fabienne; LESCOUTE, Emilien; SOLLIER, Arnaud; MERCIER, Patrick; BERNIER, Jacky (IOP Publishing, 2014)
      The propagation of laser-induced shock waves in a transparent epoxy sample is investigated by optical shadowgraphy. The shock waves are generated by a focused laser (3 ns pulse duration—1.2 to 3.4TWcm−2) producing pressure ...
    • Degradation of epoxy coatings under gamma irradiation 
      Article dans une revue avec comité de lecture
      DJOUANI, Fatma; ZAHRA, Yahya; KUNTZ, M; VERDU, Jacques; ccFAYOLLE, Bruno (Elsevier, 2014)
      Epoxy networks based on Diglycidyl ether of bisphenol A (DGEBA) and cured with Jeffamines (POPA) or polyamidoamine (PAA) were gamma irradiated at 25 1C in air. Dose rates of 50, 200 or 2000 Gy h- 1 for doses up 100 kGy ...
    • Water clustering in polychloroprene 
      Article dans une revue avec comité de lecture
      LE GAC, Pierre Yves; ROUX, Gérard; DAVIES, Peter; VERDU, Jacques; ccFAYOLLE, Bruno (Elsevier, 2014)
      Water sorption has been studied gravimetrically for polychloroprene rubber samples, first at a fixed hygrometric ratio (98% HR) and several temperatures (25, 40, 60 and 80 °C) for samples of 1.8 and 3.8 mm thickness (Constant ...
    • 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 ...
