    • Modelling the effect of particle inertia on the orientation kinematics of fibres and spheroids immersed in a simple shear flow 
      Article dans une revue avec comité de lecture
      SCHEUER, Adrien; GRÉGOIRE, Guillaume; KEUNINGS, Roland; ccABISSET-CHAVANNE, Emmanuelle; ccCHINESTA SORIA, Francisco (ELSEVIER, 2020)
      Simulations of flows containing non-spherical particles (fibres or ellipsoids) rely on the knowledge of the equation governing the particle motion in the flow. Most models used nowadays are based on the pioneering work of ...
    • Learning slosh dynamics by means of data 
      Article dans une revue avec comité de lecture
      MOYA, Beatriz; GONZÁLEZ, David; ccCUETO, Elias; ALFARO, Icíar; ccCHINESTA SORIA, Francisco (Springer Verlag, 2019)
      In this work we study several learning strategies for fluid sloshing problems based on data. In essence, a reduced-order model of the dynamics of the free surface motion of the fluid is developed under rigorous thermodynamics ...
    • Friction stir welding using unthreaded tools: Analysis of the flow 
      Article dans une revue avec comité de lecture
      LORRAIN, Olivier; ZAHROUNI, Hamid; LAWRJANIEC, Didier; ccFAVIER, Véronique (Springer Verlag, 2010)
      Friction stir welding (FSW) is a solid-phase welding process. Material flow during FSW is very complex and not fully understood. Most of studies in literature used threaded pins since most industrial applications currently ...
    • Synthesis and characterization of new membranes deriving from sulfonated polyethersulfone for PEMFC applications 
      Article dans une revue avec comité de lecture
      MABROUK, Walid; OGIER, Lionel; SOLLOGOUB, Cyrille; VIDAL, Serge; MATOUSSI, Fatma; FAUVARQUE, Jean François (FHF, 2015)
      Two new types of proton exchange membranes used in proton exchange membrane fuel cell (PEMFC) were synthesized from sulfochlorinated polyethersulfone (PES (polyarylethersulfone)–SO2Cl). One, called S-PESB, was obtained by ...
    • Propagating material instabilities in planar architectured materials 
      Article dans une revue avec comité de lecture
      VIARD, Antoine-Emmanuel; DIRRENBERGER, Justin; FOREST, Samuel (Elsevier, 2020)
      Under tension low carbon steel exhibits inhomogeneous plastic deformation. This instability called Piobert-Lüders banding creates fronts of localized strain that propagate in the structure. To date, Lüders banding has been ...
    • Structure-preserving neural networks 
      Article dans une revue avec comité de lecture
      HERNÁNDEZ, Quercus; BADÍAS, Alberto; GONZÁLEZ, David; ccCUETO, Elias; ccCHINESTA SORIA, Francisco (Elsevier, 2020)
      We develop a method to learn physical systems from data that employs feedforward neural networks and whose predictions comply with the first and second principles of thermodynamics. The method employs a minimum amount of ...
    • Cooperativity Scaling and Free Volume in Plasticized Polylactide 
      Article dans une revue avec comité de lecture
      ARAUJO, Steven; DELPOUVE, Nicolas; DOMENEK, Sandra; GUINAULT, Alain; GOLOVCHAK, Roman; SZATANIK, Roman; INGRAM, Adam; FAUCHARD, Cyrille; DELBREILH, Laurent; DARGENT, Eric (American Chemical Society, 2019)
      The experimental evidence of the increase of activation energy associated with the super Arrhenius behavior governing amorphous polylactide by free volume variations has been obtained through a combination of calorimetric, ...
