    • On the physical interpretation of fractional diffusion 
      Article dans une revue avec comité de lecture
      NADAL, Enrique; ccCUETO, Elias; ccABISSET-CHAVANNE, Emmanuelle; ccCHINESTA SORIA, Francisco (Elsevier Masson, 2018)
      Even if the diffusion equation has been widely used in physics and engineering, and its physical content is well understood, some variants of it escape fully physical understanding. In particular, anormal diffusion appears ...
    • Squeal measurement using operational deflection shape. Quality assessment and analysis improvement using FEM expansion. 
      Communication avec acte
      BALMES, Etienne; VERMOT DES ROCHES, Guillaume; CHANCELIER, Thierry; MARTIN, Guillaume (FISITA, 2017)
      In presence of squeal, Operational Deflection Shapes (ODS) are classically measured to gain understanding of brake behavior. A simple numeric example is analyzed to justify the use of time-frequency analysis and shows that ...
    • Dual PZT sizing for mode decomposition on a composite anisotropic plate 
      Communication avec acte
      LIZE, Emmanuel; BOLZMACHER, Christian; ccMECHBAL, Nazih; ccRÉBILLAT, Marc (2018)
      Structural Health Monitoring is a multidisciplinary field whose aim is to monitor damages within structures. Damages are detected by means of features - Damage Index (DI) - obtained by comparing measurements obtained from ...
    • 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 ...
