    • Hypervelocity impacts into porous graphite: experiments and simulations 
      Article dans une revue avec comité de lecture
      HEBERT, David; SEISSON, G; RULLIER, J.-L; BERTRON, I; HALLO, L; CHEVALIER, J.M; THESSIEUX, C; GUILLET, F; BERTHE, Laurent (Royal Society, The, 2017)
      We present experiments and numerical simulations of hypervelocity impacts of 0.5 mm steel spheres into graphite, for velocities ranging between 1100 and 4500 m s−1. Experiments have evidenced that, after a particular ...
    • Investigation of polyamide 11 embrittlement during oxidative degradation 
      Article dans une revue avec comité de lecture
      OKAMBA-DIOGO, Octavie; VERDU, Jacques; FERNAGUT, François; GUILMENT, Jean; ccFAYOLLE, Bruno; ccRICHAUD, Emmanuel (Elsevier, 2016)
      Embrittlement processes occurring during thermal oxidation are investigated for stabilized and unstabilized polyamide 11 samples differing by their thicknesses and initial molar masses. Tensile tests were carried out in ...
    • Neutron diffraction measurements of residual stress distribution in large zirconia based refractory bricks produced by electro-fusion and casting 
      Article dans une revue avec comité de lecture
      ÖRS, Taylan; GOURAUD, Fanny; GUINEBRETIERE, René; HUGER, Marc; MICHEL, Vincent; CASTELNAU, Olivier (Elsevier, 2017)
      Electro-fusion and casting is used to produce large refractory bricks (∼250 kg) containing a high amount of ZrO2. These bricks are used in glass-making furnaces where good mechanical performance is required at very high ...
    • Aluminum to titanium laser welding-brazing in V-shaped grooveI 
      Article dans une revue avec comité de lecture
      TOMASHCHUK, Iryna; SALLAMAND, Pierre; MÉASSON, A.; CICALA, E; DUBAND, M; ccPEYRE, Patrice (Elsevier, 2017)
      Laser assisted joining of AA5754 aluminum alloy to T40 titanium with use of Al-Si filler wires was carried out. Continuous Yb:YAG laser beam was shaped into double spot tandem and defocalized to cover larger interaction ...
    • Stress measurements by multi-reflection grazing-incidence X-ray diffraction method (MGIXD) using different radiation wavelengths and different incident angles 
      Article dans une revue avec comité de lecture
      MARCISZKO, Marianna; BACZMANSKI, Andrzej; WROBEL, Mirosław; WRONSKI, Sebastian; CIOS, Grzegorz; ccBRAHAM, Chedly (Elsevier, 2017)
      The presented study introduces the development of the multi-reflection grazing-incidence X-ray diffraction method (MGIXD) for residual stress determination. The proposed new methodology is aimed at obtaining more reliable ...
    • Effect of thermal oxidation on the self-assembly of triblock terpolymers 
      Article dans une revue avec comité de lecture
      MONTANA, Juan Sebastian; MIQUELARD-GARNIER, Guillaume; ccRICHAUD, Emmanuel; ccROLAND, Sébastien (Elsevier, 2017)
      This paper reports an investigation of the thermal degradation of a poly(styrene-b-butadiene-b-methyl methacrylate) triblock terpolymer compared with those of butadiene rubbers and poly(styrene-b-methyl methacrylate). ...
    • Simplified numerical model for the laser metal deposition additive manufacturing process 
      Article dans une revue avec comité de lecture
      PEYRE, Patrice; POUZET, Sébastien; CASTELNAU, Olivier; ccDAL, Morgan (Laser Institute of America, 2017)
      The laser metal deposition (LMD) laser technique is a free-form metal deposition process, which allows generating near net-shape structures through the interaction of a powder stream and a laser beam. A simplified numerical ...
