    • BENDING WAVES FOCUSING IN ARBITRARY SHAPED PLATE-LIKE STRUCTURES: APPLICATION TO SPATIAL AUDIO 
      Communication avec acte
      BENBARA, Nassim; ccMECHBAL, Nazih; ccRÉBILLAT, Marc (ICA, 2019)
      Advanced audio applications are more and more demanding with respect to the visual impact of loudspeakers while still requiring more channels for high quality spatial sound rendering. The use of arbitrary plate-like ...
    • Towards an industrial deployment of PZT based SHM processes: A dedicated metamodel for Lamb wave propagation 
      Communication avec acte
      POSTORINO, Hadrien; ccMONTEIRO, Eric; ccMECHBAL, Nazih; ccRÉBILLAT, Marc (2020)
      Numerical simulations of Structural Health Monitoring processes based on wave propagation can be very costly in terms of computation time, especially for complex aeronautic composite structures, and therefore strongly ...
    • Damage imaging post processing for delamination size assessment of CFRP aeronautic structures 
      Communication avec acte
      BRIAND, William; ccMECHBAL, Nazih; ccGUSKOV, Mikhail; ccRÉBILLAT, Marc (2020)
      Thanks to their high strength to mass ratio, composite materials are now widespread in the aerospace industry. Nevertheless, this type of material is sub- ject to internal damages like delamination. In order to detect and ...
    • Investigation and modelling of the water transport properties in unfilled EPDM elastomers 
      Article dans une revue avec comité de lecture
      LACUVE, Maxime; PERRIN, Lara; NOTINGHER, Petru; TOURCHER, Christophe; BEN-HASSINE, Mouna; TANZEGHTI, Houssam; ccCOLIN, Xavier (Elsevier, 2019)
      The water sorption properties (i.e. diffusivity and solubility) of three unfilled vulcanized EPDMs were investigated in wet atmosphere (typically between 0 and 95% RH) and in pure distilled water (denoted as 100% RH) at ...
    • Role of discrete intra-granular slip bands on the strain-hardening of polycrystals 
      Article dans une revue avec comité de lecture
      COLLARD, Christophe; BERVEILLER, Marcel; ccFAVIER, Véronique (Elsevier, 2010)
      This work investigates a new micromechanical modeling of polycrystal plasticity, accounting slip bands for physical plastic heterogeneities considered as periodically distributed within grains. These intra-granular plastic ...
    • Experimental and ab initio infrared study of χ-, κ- and α-aluminas formed from gibbsite 
      Article dans une revue avec comité de lecture
      FAVARO, Laurent; BOUMAZA, A.; ROY, Pascale; LÉDION, Jean; SATTONNAY, Gaël; BRUBACH, Jean Blaise; HUNTZ, Anne Marie; TÉTOT, Robert (Elsevier, 2010)
      χ-, κ- and α-alumina phases formed by dehydration of micro-grained gibbsite between 773 and 1573 K are studied using infrared spectroscopy (IR). The structural transitions evidenced by X-ray diffraction (XRD) were interpreted ...
    • Study of Bonding Formation between the Filaments of PLA in FFF Process 
      Article dans une revue avec comité de lecture
      KALLEL, Achraf; ccKOUTIRI, Imade; BABAEITORKAMANI, E.; KHAVANDI, A.; TAMIZIFAR, M.; SHIRINBAYAN, Mohammadali; ccTCHARKHTCHI, Abbas (2019)
      Fused filament fabrication (FFF) is an additive manufacturing (AM) process that provides physical objects commonly used for modeling, prototyping and production applications. The major drawback of this process is poor ...
