    • Melt Pool and Keyhole Behavior Analysis for Deep Penetration Laser Welding 
      Article dans une revue avec comité de lecture
      FABBRO, Rémy (IOP Publishing, 2010)
      One usually defines the main characteristic of the welding performances of a given laser system by its “penetration curve” that corresponds to the welding depth as a function of the welding speed Vw for a given set of ...
    • 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 ...
    • 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 ...
    • Shear-strain step response in linear regime of dilute suspensions of naturally bent carbon nanotubes 
      Article dans une revue avec comité de lecture
      CRUZ, Camilo; ILLOUL, Lounès; ccREGNIER, Gilles; ccCHINESTA SORIA, Francisco (Wiley, 2012)
      Impressive enhancements of the storage modulus have been documented when low volume fractions of single wall carbon nanotubes (SWNTs) are added to a Newtonian solvent for obtaining dilute suspensions. The intrinsic bending ...
    • On using the leveling of the free surface of a Newtonian fluid to measure viscosity and Navier slip length 
      Article dans une revue avec comité de lecture
      GILORMINI, Pierre; TEYSSEDRE, Hubert (Royal Society, The, 2013)
      Measuring the relaxation time involved in the leveling of the free surface of a Newtonian fluid laid on a substrate can give access to material parameters. It is shown here how most favorable pattern geometries of the free ...
    • 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 ...
    • Legitimate domain of a Newtonian behavior for thermal nanoimprint lithography 
      Article dans une revue avec comité de lecture
      TEYSSEDRE, Hubert; GILORMINI, Pierre; LANDIS, Stefan; ccREGNIER, Gilles (Elsevier, 2013)
      Nanoimprint lithography is an efficient way to reproduce nanostructures down to 20 nanometers in sub-micrometer polymeric films. To optimize this process, simulation using a Newtonian behavior is a cheap and efficient way ...
