    • Squeal measurement with 3D Scanning Laser Doppler Vibrometer: handling of the time varying system behavior and analysis improvement using FEM expansion 
      Communication avec acte
      MARTIN, Guillaume; CHANCELIER, Thierry; VERMOT DES ROCHES, Guillaume; BALMES, Etienne (2018)
      In the presence of squeal, Operational Deflection Shapes (ODS) are classically performed to analyze behavior. A simple numeric example is used to show that two real shapes should dominate the response. This justifies an ...
    • In situ observation of g-ZrH formation by X-ray diffraction 
      Article dans une revue avec comité de lecture
      BJERKEN, Christina; STEUWER, Axel; WANG, Z; DANIELS, J; ANDRIEUX, Jérôme; BLOMQVIST, Jakob; ZANELLATO, Olivier; MAIMAITIYILI, Tuerdi (Elsevier, 2017)
      We report on the measurement of the formation of γ-ZrH during in situ gaseous charging. The measurements were undertaken using high-energy synchrotron X-ray diffraction. Experimental observation shows that γ-ZrH can form ...
    • Laser cladding and wear testing of nickel base hardfacing materials: Influence of process parameters 
      Article dans une revue avec comité de lecture
      AUBRY, Pascal; BLANC, C; MALOT, T; MASKROT, H; ccDAL, Morgan; ccDEMIRCI, Ibrahim (Laser Institute of America, 2017)
      In fast neutron reactors, some parts can be subjected to displacements between each other (as movable parts for example). On these parts, the contact areas usually need a hardfacing coating. The standard hardfacing alloy ...
    • Simulation of the Oxygen Permeability of a Composite Container 
      Article dans une revue avec comité de lecture
      DEFAUCHY, Virginie; LE CORRE, Hélène; ccCOLIN, Xavier (MDPI, 2018)
      A kinetic model has been derived from the classical (Fick and Henry’s) laws of the gas theory for predicting the oxygen permeability of a closed composite container, initially filled by pure nitrogen under a pressure ...
    • Void coalescence in porous ductile solids containing two populations of cavities 
      Article dans une revue avec comité de lecture
      MORIN, Léo; MICHEL, Jean-Claude (Elsevier, 2018)
      A model of coalescence by internal necking of primary voids is developed which accounts for the presence of a second population of cavities. The derivation is based on a limit-analysis of a cylindrical cell containing a ...
    • Evidence of 3D strain gradients associated with tin whisker growth 
      Article dans une revue avec comité de lecture
      HEKTOR, Johan; MARIJON, Jean-Baptiste; RISTINMAA, Matti; HALL, Stephen A.; HALLBERG, Hakan; SRINIVASAN, Iyengar; MICHA, Jean-Sébastien; ROBACH, Odile; GRENNERAT, Fanny; CASTELNAU, Olivier (Elsevier, 2018)
      We have used Differential Aperture X-ray Microscopy (DAXM) to measure grain orientations and deviatoric elastic strains in 3D around a tin whisker. The results show strain gradients through the depth of the tin coating, ...
    • 3D printing using concrete extrusion: A roadmap for research 
      Article dans une revue avec comité de lecture
      BUSWELL, Richard A.; LEAL DE SILVA, Wilson R.; JONES, S.Z.; DIRRENBERGER, Justin (Elsevier, 2018)
      Large-scale additive manufacturing processes for construction utilise computer-controlled placement of extruded cement-based mortar to create physical objects layer-by-layer. Demonstrated applications include component ...
