    • A statistical theory of polymer network degradation 
      Article dans une revue avec comité de lecture
      GILORMINI, Pierre; VERDU, Jacques; ccRICHAUD, Emmanuel (Elsevier, 2014)
      A statistical theory was proposed for the degradation (random scission of chains) of a network having f-functional nodes in the case where all chains contain equireactive groups and a chain scission event does not create ...
    • Finite element analysis of laser shock peening of 2050-T8 aluminum alloy 
      Article dans une revue avec comité de lecture
      HFAIEDH, Neila; PEYRE, Patrice; SONG, Hongbin; POPA, Ioana; JI, Vincent; VIGNAL, Vincent (Elsevier, 2015)
      Laser shock processing is a recently developed surface treatment designed to improve the mechanical properties and fatigue performance of materials, by inducing a deep compressive residual stress field. The purpose of this ...
    • Physical interpretation of the Mullins softening in a carbon-black filled SBR 
      Article dans une revue avec comité de lecture
      DIAZ, Rodrigo; DIANI, Julie; GILORMINI, Pierre (Elsevier, 2014)
      A 40 phr carbon-black filled styrene butadiene rubber has been submitted to several experiments in order to identify the physical damage responsible for the mechanical softening recorded upon first stretch. Damage in the ...
    • 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. ...
    • 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 ...
    • Dynamic cratering of graphite : experimental results and simulations 
      Article dans une revue avec comité de lecture
      SEISSON, G; HEBERT, David; BERTRON, I; CHEVALIER, J.M; HALLO, L; LESCOUTE, Emilien; VIDEAU, Laurent; COMBIS, Patrick; GUILLET, F; BOUSTIE, Michel; BERTHE, Laurent (Elsevier, 2013)
      The cratering process in brittle materials under hypervelocity impact (HVI) is of major relevance for debris shielding in spacecraft or high-power laser applications. Amongst other materials, carbon is of particular interest ...
    • Review : Auto-oxidation of aliphatic polyamides 
      Article dans une revue avec comité de lecture
      OKAMBA-DIOGO, Octavie; VERDU, Jacques; GUILMENT, Jean; FERNAGUT, François; ccFAYOLLE, Bruno; ccRICHAUD, Emmanuel (Elsevier, 2013)
      The literature on oxidation kinetics of polyamides and model compounds has been reviewed in order to try to extract suitable information for non-empirical kinetic modeling. Polyamide characteristics are systematically ...
