    • Dynamic cratering of graphite : experimental results and simulations 
      Article dans une revue avec comité de lecture
      SEISSON, G; HEBERT, David; BERTRON, I; CHEVALIER, J.M; HALLO, L; LESCOUTE, Emilien; VIDEAU, Laurent; COMBIS, Patrick; GUILLET, F; BOUSTIE, Michel; BERTHE, Laurent (Elsevier, 2013)
      The cratering process in brittle materials under hypervelocity impact (HVI) is of major relevance for debris shielding in spacecraft or high-power laser applications. Amongst other materials, carbon is of particular interest ...
    • Laser Ignition of Bulk Iron, Mild Steel, and Stainless Steel in Oxygen Atmospheres 
      Article dans une revue avec comité de lecture
      MULLER, Maryse; EL-RABII, Hazem; FABBRO, Rémy (Taylor & Francis, 2014)
      The ignition of pure iron, mild steel S355J, and stainless steel 316L has been investigated. The whole ignition and combustion processes have been monitored using a high-speed video camera and adapted pyrometry. Our results ...
    • Assessment of low cycle fatigue improvement of machined AISI 316 stainless steel by brush hammering 
      Article dans une revue avec comité de lecture
      SIDHOM, Naziha; MAKHLOUF, Kamel; KHLIFI, Ammar; SIDHOM, Habib; ccBRAHAM, Chedly (Wiley-Blackwell, 2014)
      The effects of wire brush hammering on low cycle fatigue behaviour of AISI 316 austenitic stainless steel has been investigated on turned samples through an experimental study combining strain controlled fatigue tests, ...
    • Understanding friction induced damping in bolted assemblies through explicit transient simulation 
      Communication avec acte
      VERMOT DES ROCHES, Guillaume; BALMES, Etienne (KUL, 2014)
      The design of joints is seeing increased interest as one of the ways of controlling damping levels in lighter and more flexible aeronautic structures. Damping induced by joint dissipation has been studied for more than a ...
    • Improved Modal Assurance Criterion using a quantification of identification errors per mode/sensor 
      Communication avec acte
      MARTIN, Guillaume; BALMES, Etienne; CHANCELIER, Thierry (KUL, 2014)
      Scanning laser vibrometer measurements generate detailed maps of modal characteristics in normal or 3D directions. Since many points are measured, individual validation of cannot be performed manually in a reasonable time ...
    • Simulation of a finishing operation : milling of a turbine blade and influence of damping 
      Communication avec acte
      COFFIGNAL, Gérard; BALMES, Etienne; TEXIER, Anthony; ccLORONG, Philippe; ccGUSKOV, Mikhail (ASME, 2012)
      Milling is used to create very complex geometries and thin parts, such as turbine blades. Irreversible geometric defects may appear during finishing operations when a high surface quality is expected. Relative vibrations ...
    • Finite element analysis of laser shock peening of 2050-T8 aluminum alloy 
      Article dans une revue avec comité de lecture
      HFAIEDH, Neila; PEYRE, Patrice; SONG, Hongbin; POPA, Ioana; JI, Vincent; VIGNAL, Vincent (Elsevier, 2015)
      Laser shock processing is a recently developed surface treatment designed to improve the mechanical properties and fatigue performance of materials, by inducing a deep compressive residual stress field. The purpose of this ...
