    • Penetration and cratering experiments of graphite by 0.5-mm diameter steel spheres at various impact velocities 
      Article dans une revue avec comité de lecture
      SEISSON, G; HEBERT, D; HALLO, L; CHEVALIER, J.M; GUILLET, F; BERTHE, Laurent; BOUSTIE, Michel (Elsevier, 2014)
      Cratering experiments have been conducted with 0.5-mm diameter AISI 52100 steel spherical projectiles and 30-mm diameter, 15-mm long graphite targets. The latter were made of a commercial grade of polycrystalline and porous ...
    • Investigation of delamination mechanisms during a laser drilling on a cobalt-base superalloy 
      Article dans une revue avec comité de lecture
      BERTHE, Laurent; ccSCHNEIDER, Matthieu; ccFAVIER, Véronique; ccGIRARDOT, Jeremie (Elsevier, 2013)
      Temperatures in the high pressure chamber of aircraft engines are continuously increasing to improve the engine efficiency. As a result, constitutive materials such as cobalt and nickel-base superalloys need to be thermally ...
    • Design oriented simulation of contact-friction instabilities in application to realistic brake assemblies 
      Communication avec acte
      VERMOT DES ROCHES, Guillaume; BALMES, Etienne; LEMAIRE, Rémi; PASQUET, Thierry (2010)
      This paper presents advances in non-linear simulations for systems with contact-friction, with an application to brake squeal. A method is proposed to orient component structural modifications from brake assembly simulations ...
    • Dynamic cratering of graphite: Experimental results and simulations 
      Article dans une revue avec comité de lecture
      HEBERT, David; BERTRON, I; CHEVALIER, J.M; HALLO, L; LESCOUTE, Emilien; VIDEAU, Laurent; COMBIS, Patrick; GUILLET, F; BERTHE, Laurent; SEISSON, G.; BOUSTIE, Michel (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 ...
    • Shock adhesion test for composite bonded assembly using a high pulsed power generator 
      Article dans une revue avec comité de lecture
      GAY, Elise; BERTHE, Laurent; BUZAUD, Eric; BOUSTIE, Michel; ARRIGONI, Michel (American Institute of Physics, 2013)
      In a context of the rising use of composite assemblies in aeronautic or defense fields, the assessment of their strength is a key issue. The method developed in this study attempts to provide solutions. A shock adhesion ...
    • NON-LINEAR OBSERVER-BASED CONTROL OF FLEXIBLE-JOINT MANIPULATORS USED IN MACHINE PROCESSING 
      Communication avec acte
      QIN, Jinna; LEONARD, François; ABBA, Gabriel (ASME, 2012)
      This paper proposes to use a non-linear observer to build the state and the external force of flexible manipulator robots during their machining (composite materials) processes or Friction Stir Welding (FSW) processes. ...
    • Identification du modèle avec flexibilité : méthode et paramètres numériques 
      Rapport de recherche
      GAUTIER, Maxime; JUBIEN, Anthony; ABBA, Gabriel; QIN, Jinna (ENSAM, 2013)
      Ce rapport est décomposé en 8 parties. La seconde partie rappelle les bases de la modélisation des robots à architecture série et présente les modélisations des deux robots. La troisième présente les méthodes d'identification ...
