    • Laser heat treatment of martensitic steel and dual-phase steel with high martensite content 
      Article dans une revue avec comité de lecture
      LAPOUGE, Pierre; DIRRENBERGER, Justin; COSTE, Frédéric; ccSCHNEIDER, Matthieu (Elsevier, 2019)
      Laser heat treatment of galvanised steels with a martensite content superior to 80% were performed on a 1 cm wide area over an extensive temperature range [620 K - 1350 K]. The material softening induced is studied through ...
    • Very high cycle fatigue for single phase ductile materials: Comparison between α-iron, copper and α-brass polycrystals 
      Article dans une revue avec comité de lecture
      BLANCHE, Antoine; WANG, Chong; PHUNG, Ngoclam; WAGNER, Daniele; BATHÌAS, Claude; CHRYSOCHOOS, André; MUGHRABI, Haeel; ccRANC, Nicolas; ccFAVIER, Véronique (Elsevier, 2016)
      In this paper, the main results obtained in the framework of a National French Agency project called DISFAT, standing for “Dissipation in Fatigue”, are presented. The project was dedicated to the microplastic mechanisms ...
    • Representative volume element size determination for viscoplastic properties in polycrystalline materials 
      Article dans une revue avec comité de lecture
      DIRRENBERGER, Justin; ccMONTEIRO, Eric; ccRANC, Nicolas (Elsevier, 2019)
      The size of representative volume element (RVE) for 3D polycrystalline material is investigated. A statistical RVE size determination method is applied to a Voronoi tessellation-based pure copper microstructure. The ...
    • Ultrafine versus coarse grained Al 5083 alloys: From low-cycle to very-high-cycle fatigue 
      Article dans une revue avec comité de lecture
      LI, Meng; ANCHAL, Goyal; DOQUET, Véronique; COUZINIÉ, Jean-Philippe; ccRANC, Nicolas (Elsevier, 2019)
      The fatigue performance of coarse and ultrafine-grained (UFG) 5083 Al alloy were compared, from low to very high cycle fatigue. The UFG alloy exhibited cyclic hardening and predominant kinematic hardening. At high plastic ...
    • Development of the symmetrical laser shock test for weak bond inspection 
      Article dans une revue avec comité de lecture
      SAGNARD, Maxime; ECAULT, Romain; BERTHE, Laurent; BRUNE, Kay (Elsevier, 2019)
      This study aims to assess the capability of the LAser Shock Adhesion Test to detect weak bonds in assemblies made of carbon fibre reinforced polymer laminates as well as understand the behaviour of different bonded composite ...
    • Scaling laws for the laser welding process in keyhole mode 
      Article dans une revue avec comité de lecture
      FABBRO, Rémy (Elsevier, 2019)
      This study shows that the keyhole model derived for determining the scaling laws of keyhole depths for laser welding when high power incident laser beams are used (typically in the multi-kW incident power range), can be ...
    • Laser induced dynamic fracture of fused silica: Experiments and simulations 
      Article dans une revue avec comité de lecture
      DEREURE, Corentin; HALL, R.; BABER, Forrest; LOISON, Didier; LESCOUTE, Emilien; GUIN, Jean-Pierre; SANGLEBŒUF, Jean Christophe; BERTHE, Laurent; NIVARD, Mariette; GUVEN, Ibrahim (Elsevier, 2019)
      Fused silica samples were subjected to laser induced shock loading. Laser flux was varied in order to obtain different amounts and characteristics of damage in the samples. Three dimensional damage and fracture maps of two ...
