    • 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 ...
    • Experimental investigation of hydrodynamics of melt layer during laser cutting of steel 
      Article dans une revue avec comité de lecture
      HIRANO, Koji; FABBRO, Rémy (IOP Publishing, 2011)
      In laser cutting process, understanding of hydrodynamics of melt layer is significant, because it is an important factor which controls the final quality. In this work, we observed hydrodynamics of melt layer on kerf front ...
    • 3D heat transfer model of hybrid laser Nd : Yag-MAG welding of a S355 steel and experimental validation 
      Article dans une revue avec comité de lecture
      LE GUEN, Emilie; CARIN, Muriel; FABBRO, Rémy; COSTE, Frédéric; LE MASSON, Philippe (Elsevier, 2011)
      A three-dimensional heat transfer model was developed to predict the temperature fields, the weld geometry and the shape of the solidified weld reinforcement surface during hybrid laser-MAG arc welding of fillet joints. ...
    • Possible explanations for different surface quality in laser cutting with 1 micron and 10 microns beams 
      Article dans une revue avec comité de lecture
      HIRANO, Koji; FABBRO, Rémy (Laser Institute of America, 2012)
      In laser　cutting　of　thick　steel　sheets,　quality　difference　is　observed　between　cut　surfaces　obtained　with 1 micron and 10 micron laser beams. This paper investigates physical mechanisms for this interesting and important ...
    • 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 ...
