    • Behavior of basalt under laser-induced shock-wave application to the planetary hypervelocity impact effect 
      Article dans une revue avec comité de lecture
      BERTHE, Laurent; BEZAEVA, Natalia S.; GATTACECA, Jerôme; BOUSTIE, Michel; DE RESŚGUIER, Thibaut; ROCHETTE, Pierre (Laser Institute of America, 2011)
      This paper presents the results of an investigation of the impact of laser-induced shock on basalt samples in a water confinement regime. In order to observe the effect of laser shock-wave propagation, in this material, ...
    • Fracture behaviour of a polypropylene film 
      Article dans une revue avec comité de lecture
      CHEMINGUI, Mahmoud; VERDU, Jacques; FEROUANI, Abdel Karim; LEFEBVRE, Jean–Marc Marc R.; ccFAYOLLE, Bruno (Elsevier, 2011)
      Ageing of polymers results from structural modifications at the molecular scale and kinetic modelling must be elaborated from analysis of the phenomenon at this scale. However, the change of mechanical properties results ...
    • Microstructures and rheology of the Earth's upper mantle inferred from a multiscale approach 
      Article dans une revue avec comité de lecture
      CASTELNAU, Olivier; CORDIER, Patrick; LEBENSON, RA; MERKEL, SEBASTIEN; RATERRON, PAUL (Centre Mersenne, 2010)
      The strongly anisotropic rheology of olivine polycrystals, associated to their microstructure, constitutes a key feature affecting the dynamics of the Earth's upper mantle. High pressure deformation experiments carried out ...
    • Texture control of 316L parts by modulation of the melt pool morphology in selective laser melting 
      Article dans une revue avec comité de lecture
      ANDREAU, Olivier; PEYRE, Patrice; PENOT, Jean-Daniel; DE TERRIS, Thibaut; DUPUY, Corinne; BAUDIN, Thierry; ccKOUTIRI, Imade; ccPESSARD, Etienne; ccSAINTIER, Nicolas (Elsevier, 2019)
      In this study, 316L parts were fabricated with the selective laser melting additive layer manufacturing process using unidirectional laser scan to control their texture. The melt pool shape, microstructure and texture of ...
    • Prediction and sensitivity analysis of bubble dissolution time in 3D selective laser sintering using ensemble decision trees 
      Article dans une revue avec comité de lecture
      LY, Haibang; LE, Tien Thinh; LE, Vuongminh; PHAM, Binh Thai; ccDAL, Morgan; ccREGNIER, Gilles; ccMONTEIRO, Eric (MDPI, 2019)
      The presence of defects like gas bubble in fabricated parts is inherent in the selective laser sintering process and the prediction of bubble shrinkage dynamics is crucial. In this paper, two artificial intelligence (AI) ...
    • Localized Atomic Segregation in the Spalled Area of a Zr50Cu40Al10 BMG Induced by Laser-shock Experiment 
      Article dans une revue avec comité de lecture
      JODAR, Benjamin; LOISON, Didier; YOKOYAMA, Yoshihiko; LESCOUTE, Emilien; NIVARD, Mariette; BERTHE, Laurent; SANGLEBŒUF, Jean Christophe (IOP Publishing, 2017)
      Laser-shock experiments were performed on a ternary Zr50Cu40Al10bulk metallic glass. A spalling process was studied through post-mortem analyses conducted on a recovered sample and spall. Scanning electron microscopy ...
    • Laser based method for surface tension and density measurements for liquid refractory metals (Nb, Ta, and W) 
      Article dans une revue avec comité de lecture
      COSTE, Frédéric; BOLIS, Riccardo; FABBRO, Rémy; ccDAL, Morgan; ccSCHNEIDER, Matthieu (Laser Institute of America, 2019)
      The increase of process simulations in industry leads to the need of accurate knowledge of material thermal properties. As the determination of liquid metal properties is quite difficult, this article presents an experimental ...
