    • Simulation numérique du perçage laser par la méthode C-NEM 
      Communication avec acte
      ILLOUL, Lounès; BERTHE, Laurent; ccLORONG, Philippe; ccRANC, Nicolas; ccSCHNEIDER, Matthieu; ccFAVIER, Véronique; ccGIRARDOT, Jeremie (2012)
      Ces travaux présentent une alternative numérique au problème de simulation du procédé de perçage par laser. L’utilisation des éléments finis pour modéliser la propagation du trou au cours du temps montre des limites ...
    • Simulation of the laser drilling process with the Constraint Natural Element Method 
      Communication avec acte
      ILLOUL, Lounès; BERTHE, Laurent; ccLORONG, Philippe; ccRANC, Nicolas; ccSCHNEIDER, Matthieu; ccFAVIER, Véronique; ccGIRARDOT, Jeremie (2012)
      These works present a numerical alternative to the simulation of the laser drilling process. The use of the finite element method to modeling the hole creation during a laser pulse shows difficulties in front of a moving ...
    • Transparent conductive Nd-doped ZnO thin films 
      Article dans une revue avec comité de lecture
      NISTOR, M; MILLON, E; CACHONCINLLE, C; SEILER, Wilfrid; JEDRECY, N.; HEBERT, C; PERRIERE, J. (IOP Publishing, 2015)
      Transparent Nd-doped ZnO films with thickness in the range of 70 to 250 nm were grown by pulsed-laser deposition (PLD) on c-cut sapphire substrates at various oxygen pressures and substrate temperatures. A wide range of ...
    • Epitaxial growth of gallium oxide films on c-cut sapphire substrate 
      Article dans une revue avec comité de lecture
      SEILER, Wilfrid; SELMANE, M; ABDELOUHADI, K; PERRIÈRE, J (Elsevier, 2015)
      The nature of the crystalline phase present in gallium oxide films grown by pulsed-laser deposition on c-cut sapphire substrate has been studied. Amorphous, polycrystalline or epitaxial gallium oxide films can be obtained ...
    • Exponential sine sweeps for the autonomous estimation of nonlinearities and errors assessment by bootstrap Application to thin vibrating structures 
      Article dans une revue avec comité de lecture
      EGE, Kerem; GALLO, Maxime; ANTONI, Jérôme; ccRÉBILLAT, Marc (American Society of Mechanical Engineers, 2015)
      Vibrating structures are generally assumed to behave linearly and in a noise-free environment. This is in practice not perfectly the case. First, nonlinear phenomena such as jump phenomenon, hysteresis or internal resonance ...
    • Comparison of damage behaviour of different plant fibre composites under laser impact loading 
      Article dans une revue avec comité de lecture
      TOUCHARD, Fabienne; BERTHE, Laurent; MALINOWSKI, Paweł H; OPOKA, Szymon; BOUSTIE, Michel; CHOCINSKI-ARNAULT, Laurence; OSTACHOWICZ, Wiesław M. (EDP Sciences, 2015)
      The high strain rate behaviour of the eco-composites, when submitted to laser impact loading, is not well known yet. Crucial questions are still open: influence of plant fiber length and distribution on the composite impact ...
    • Oxidative solution polymerization of aniline hydrochloride onto electrospun nanofibers mats of polylactic acid: Preparation method and characterization 
      Article dans une revue avec comité de lecture
      AL-JALLAD, Mazen; ATASSI, Yomen; MOUNIF, Eskandar; ARESSY, Matthieu; ccTCHARKHTCHI, Abbas (Wiley, 2014)
      In this work, we present the preparation of polylactic acid (PLLA)/polyaniline (PANI) conductive composite nanofibers mats. They are prepared by bulk oxidative solution polymerization of PANI onto electrospun non-woven ...
