    • Polyethylene loss of ductility during oxidation: Effect of initial molar mass distribution 
      Article dans une revue avec comité de lecture
      REANO, Armando F.; GUINAULT, Alain; ccFAYOLLE, Bruno; ccRICHAUD, Emmanuel (Elsevier, 2018)
      This paper reports a study of thermal oxidation induced embrittlement in several polyethylene grades differing mainly by the broadness of the molar mass distribution (ranging for lower than 3 to more than 30). Thermal ...
    • How to model orthotropic materials by the Discrete Element Method (DEM): random sphere packing or regular cubic arrangement? 
      Article dans une revue avec comité de lecture
      CURTI, Rémi; ccLORONG, Philippe; ccPOT, Guillaume; ccGIRARDON, Stéphane (Springer Verlag, 2019)
      The discrete element method (DEM) is used for continuous material modeling. The method is based on discretizing mass material into small elements, usually spheres, which are linked to their neighbours through bonds. If DEM ...
    • 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 ...
    • Numerical Modeling of Iceberg Capsizing Responsible for Glacial Earthquakes 
      Article dans une revue avec comité de lecture
      SERGEANT, Amandine; YASTREBOV, Vladislav; MANGENEY, Anne; CASTELNAU, Olivier; MONTAGNER, Jean-Paul; STUTZMANN, Eléonore (American Geophysical Union/Wiley, 2018)
      The capsizing of icebergs calved from marine‐terminating glaciers generate horizontal forces on the glacier front, producing long‐period seismic signals referred to as glacial earthquakes. These forces can be estimated by ...
    • From Architectured Materials to Large-Scale Additive Manufacturing 
      Ouvrage scientifique
      DIRRENBERGER, Justin (Springer International Publishing, 2018)
      The classical material-by-design approach has been extensively perfected by materials scientists, while engineers have been optimising structures geometrically for centuries. The purpose of architectured materials is to ...
    • 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 ...
    • Propellant cohesive fracture during the peel test of a propellant/liner structure 
      Article dans une revue avec comité de lecture
      TOULEMONDE, Paul-Aymé; GILORMINI, Pierre; JULIE, Diani; DESGARDIN, Nancy; NEVIÈRE, Robert (Taylor & Francis, 2018)
      The integrity of propellant/liner structures in rocket motors is critical to ensure controlled combustion of the engine. In an effort to improve the bonding between the liner and the propellant, it is necessary to characterize ...
