    • Multiscale modeling of upper mantle plasticity: From single-crystal rheology to multiphase aggregate deformation 
      Article dans une revue avec comité de lecture
      RATERRON, Paul; DETREZ, Fabrice; CASTELNAU, Olivier; BOLLINGER, Caroline; CORDIER, Patrick; MERKEL, Sébastien (Elsevier, 2014)
      We report a first application of an improved second-order (SO) viscoplastic self-consistent model for multiphase aggregates, applied to an olivine + diopside aggregate as analogue for a dry upper mantle peridotite deformed ...
    • 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 ...
    • Some New Concepts of Shape Memory Effect of Polymers 
      Article dans une revue avec comité de lecture
      ABDALLAH-ELHIRTSI, Sofiane; EBRAHIMI, Kambiz; SHIRINBAYAN, Mohammadali; FARZANEH, Sedigheh; ccTCHARKHTCHI, Abbas; ccFITOUSSI, Joseph (MDPI, 2014)
      In this study some new concepts regarding certain aspects related to shape memory polymers are presented. A blend of polylactic acid (PLA) (80%) and polybutylene succinate (PBS) (20%) was prepared first by extrusion, then ...
    • Effect of interlamellar spacing on the elastoplastic behavior of C70 pearlitic steel: Experimental results and self-consistent modeling 
      Article dans une revue avec comité de lecture
      YAHYAOUI, Houda; SIDHOM, H; BACZMANSKI, Andrzej; ccBRAHAM, Chedly (Elsevier, 2014)
      The effect of pearlite microstructure characteristics on strength and deformation of C70 pearlitic steel was investigated. Tensile tests under X-ray diffraction coupled with self-consistent model have been used to identify ...
    • Impact of Oxygen Transport Properties on Polypropylene Thermal Oxidation, Part 1: Effect of Oxygen Solubility 
      Article dans une revue avec comité de lecture
      FRANÇOIS-HEUDE, Alexandre; GUINAULT, Alain; DESNOUX, Eric; ccCOLIN, Xavier; ccRICHAUD, Emmanuel (Wiley, 2014)
      A general kinetic model is proposed to describe the polypropylene thermal oxidation of thin polypropylene films in a wide range of temperatures (from 60 to 200°C) and oxygen partial pressures (from 0.02 to 5 MPa) using a ...
    • Influence of temperature, UV-light wavelength and intensity on polypropylene photothermal oxidation 
      Article dans une revue avec comité de lecture
      FRANCOIS-HEUDE, Alexandre; DESNOUX, Eric; ccCOLIN, Xavier; ccRICHAUD, Emmanuel (Elsevier, 2014)
      A criterion based on the energy absorbed by photosensitive species was proposed to describe the contribution of UV-light to the initiation of the polypropylene photothermal oxidation whatever the light source. The calculation ...
    • Damage Tolerant Active Contro l: Concept and State of the Art 
      Conférence invitée
      NOBREGA, Euripedes; ccMECHBAL, Nazih (IFAC, 2012)
      Damage tolerant active control is a new research area relating to fault tolerant control design applied to mechanical structures. It encompasses several techniques already used to design controllers and to detect and to ...
