    • Rapid crack propagation in PA11: An application to pipe structure 
      Article dans une revue avec comité de lecture
      FOND, Christophe; HOCHSTETTER, Gilles; ccKOPP, Jean-Benoit (Elsevier, 2018)
      Dynamic fracture mechanism in Polyamide 11 (PA11) material has been described at laboratory scale to access to an intrinsic material parameter. A liquid transportation application is considered with polymer pipes. A ...
    • In situ X-ray tomography investigation on damage mechanisms in short glass fibre reinforced thermoplastics: Effects of fibre orientation and relative humidity 
      Article dans une revue avec comité de lecture
      ROLLAND, Héloise; ccSAINTIER, Nicolas; WILSON, Pablo; MERZEAU, Jonathan; ROBERT, Gilles (Elsevier, 2017)
      Damage mechanisms of reinforced polyamide 6,6 have been studied in 3D through in situ X-ray tomography tensile tests. 3D pictures of the microstructure have been taken during tensile tests to catch damage evolution in the ...
    • Breaking pharmaceutical tablets with a hole: Reevaluation of the stress concentration factor and influence of the hole size 
      Article dans une revue avec comité de lecture
      CROQUELOIS, Benjamin; ccGIRARDOT, Jeremie; ccKOPP, Jean-Benoit; CAZAUTETS, Clément; TCHORELOFF, Pierre; MAZEL, Vincent (Elsevier, 2017)
      Mechanical strength is an important property for pharmaceutical tablets. Its study using the theory of linear elastic fracture mechanics has been introduced in the pharmaceutical field through the Brittle Fracture Index ...
    • Crack path in aeronautical titanium alloy under ultrasonic torsion loading 
      Article dans une revue avec comité de lecture
      NIKITIN, Alexander; BATHIAS, Claude; ccPALIN-LUC, Thierry; SHANYAVSKIY, Andrey (Università di Cassino, 2015)
      This paper discusses features of fatigue crack initiation and growth in aeronautical VT3-1 titanium alloy under pure torsion loading in gigacycle regime. Two materials: extruded and forged VT3-1 titanium alloys were studied. ...
    • Very high cycle fatigue strength and crack growth of thin steel sheets 
      Article dans une revue avec comité de lecture
      OUARABI, Mohand; PEREZ MORA, Ruben; BATHIAS, Claude; ccPALIN-LUC, Thierry (Università di Cassino, 2016)
      For basic observations or for industrial applications it is of interest to use flat specimens at very high frequency in the gigacycle regime. In this work, thin flat sheet, with 1.2 mm thickness of a complex phase ...
    • Effect of the plasticity model on the yield surface evolution after abrupt strain-path changes 
      Communication avec acte
      YANG, Yanfeng; ccBAUDOUIN, Cyrille; ccBALAN, Tudor (IOP Publishing, 2018)
      Abrupt strain path changes without elastic unloading have been used in the literature to investigate the yield surface of sheet metals, both experimentally and theoretically. Such pioneering studies emphasized an apparent ...
    • Liquid plug formation in an airway closure model 
      Article dans une revue avec comité de lecture
      ROMANÒ, Francesco; FUJIOKA, H.; MURADOGLU, M.; GROTBERG, J. B. (American Physical Society, 2019)
      The closure of a human lung airway is modeled as an instability of a two-phase flow in a pipe coated internally with a Newtonian liquid. For a thick enough coating, the Plateau-Rayleigh instability creates a liquid plug ...
