    • Limitations of simple flow models for the simulation of nanoimprint 
      Article dans une revue avec comité de lecture
      TEYSSEDRE, Hubert; GILORMINI, Pierre; ccREGNIER, Gilles (2013)
      A quick evaluation of the forces involved in nanoimprint would be very helpful in the prevention of mold deflection. Unfortunately, it is shown here that assuming simplified flows may lead to quite incorrect evaluations ...
    • Measurement of laser absorptivity for operating parameters characteristic of laser drilling regime 
      Article dans une revue avec comité de lecture
      BERTHE, Laurent; FABBRO, Rémy; MULLER, Maryse; ccSCHNEIDER, Matthieu (IOP Publishing, 2008)
      Laser drilling in the percussion regime is commonly used in the aircraft industry to drill sub-millimetre holes in metallic targets. Characteristic laser intensities in the range of 10 MW cm−2 are typically employed for ...
    • A fast method for morphological analysis of laser drilling holes 
      Article dans une revue avec comité de lecture
      BERTHE, Laurent; MULLER, Maryse; FABBRO, Rémy; ccSCHNEIDER, Matthieu (Laser Institute of America, 2010)
      This paper presents an original method for analyzing laser drilled holes. The so-called Direct Observation of Drilled hOle (DODO) method is introduced and its applications. The hole characterization that’s been made is ...
    • Gas investigation for laser drilling 
      Article dans une revue avec comité de lecture
      BERTHE, Laurent; FABBRO, Rémy; MULLER, Maryse; NIVARD, Mariette; ccSCHNEIDER, Matthieu (Laser Institute of America, 2007)
      This article deals with the gas effect on percussion laser drilling in ms pulse duration range. On the one hand, the flow of assistance gas jet is investigated with and without a target using a strioscopy setup and Pitot’s ...
    • Detection of structural damage using the exponential sine sweep method 
      Communication avec acte
      HAJRYA, Rafik; ccMECHBAL, Nazih; ccRÉBILLAT, Marc (DEStech Publications, Inc., 2013)
      Structural damages can result in nonlinear dynamical responses. Thus, estimating the nonlinearities generated by damages potentially allows detecting them. In this paper, an original approach called the ES2D (Exponential ...
    • Analysis of laser shock waves and resulting surface deformations in an Al-Cu-Li aluminium alloy 
      Article dans une revue avec comité de lecture
      ccPEYRE, Patrice; BERTHE, Laurent; VIGNAL, Vincent; POPA, Ioana; BAUDIN, Thierry (IOP Publishing, 2012)
      Laser shock processing (LSP) is now a recognized surface treatment for improving fatigue or corrosion behaviour of metallic materials through the generation of a compressive stress field. In turn, the analysis of shock ...
    • Polypropylene stabilization by hindered phenols – Kinetic aspects 
      Article dans une revue avec comité de lecture
      VERDU, Jacques; ccFAYOLLE, Bruno; ccRICHAUD, Emmanuel (Elsevier, 2011)
      This article deals with polypropylene stabilization by hindered 2,6-di-tert-butylphenols. Two aspects are mainly considered: the influence of stabilizer structure, of its concentration and temperature on induction period ...
