    • Sensitivity analysis of catenary geometry on current collection quality 
      Communication avec acte
      VO VAN, Olivier; BALMES, Etienne; CAPITAINE, Arnaud; LORANG, Xavier (Civil-Comp Press, 2016)
      A global sensitivity analysis is led on catenary parameters such as dropper lengths, height of the messenger wire at masts and mechanical tensions in the wires thanks to the Sobol indices. All parameters are defined using ...
    • Validation and verification of FE models of piezo based SHM systems 
      Communication avec acte
      BALMES, Etienne; BIANCHI, Jean-Philippe; ccGUSKOV, Mikhail (2016)
      The idea of generating and sensing Lamb waves through piezoelectric sensor/actuator configurations is common for Structural Health Monitoring (SHM) applications. Methods using time of flight analysis require the prediction ...
    • Error localization and updating of junction properties for an engine cradle model 
      Communication avec acte
      VERMOT DES ROCHES, Guillaume; BALMES, Etienne; NACIVET, Samuel (2016)
      Extending the bandwidth of validity of FEM models used in vibroacoustic design is a generic objective of model generation processes. Achieving this objective requires a critical review of both testing and modeling processes. ...
    • Quantification of hindered phenols in polyamide 11 during thermal aging 
      Article dans une revue avec comité de lecture
      OKAMBA-DIOGO, Octavie; VERDU, Jacques; FERNAGUT, François; GUILMENT, Jean; PERY, Frédérique; ccFAYOLLE, Bruno; ccRICHAUD, Emmanuel (Elsevier, 2016)
      Polyamide 11 films stabilized by Irganox® 1098, Irganox® 1010 or Irganox® 245 were subjected to thermal oxidation at 110°C. The residual phenol content was assessed by comparing three analytical methods:high performance ...
    • Implicit implementation and consistent tangent modulus of a viscoplastic model for polymers 
      Article dans une revue avec comité de lecture
      ACHOUR, Nadia; CHATZIGEORGIOU, George; ccMERAGHNI, Fodil; CHEMISKY, Yves; ccFITOUSSI, Joseph (Elsevier, 2015)
      In this work, the phenomenological viscoplastic DSGZ model (Duan et al., 2001 [13]), developed for glassy or semi-crystalline polymers, is numerically implemented in a three-dimensional framework, following an implicit ...
    • Determination of cavitation load spectra—Part 2: Dynamic finite element approach 
      Article dans une revue avec comité de lecture
      ROY, Samir Chandra; FRANC, Jean-Pierre; ccRANC, Nicolas; FIVEL, Marc (Elsevier, 2015)
      Cavitation erosion is a well-known problem in fluid machineries which occurs due to repeated hydrodynamic impacts caused by cavitation bubble collapse. Cavitation pitting test is often used for the quantification of flow ...
    • Peculiar effective elastic anisotropy of nanometric multilayers studied by surface Brillouin scattering 
      Article dans une revue avec comité de lecture
      FAURIE, D; DJEMIA, P; CASTELNAU, Olivier; BRENNER, Renald; BELLIARD, L; GOUDEAU, P; RENAULT, P.-O; LE BOURHIS, E (Elsevier, 2015)
      We show in this paper by using a two-scale transition model that the elastic anisotropy of a thin film specimen can be tuned by appropriate stacking design. The anisotropic behaviour is illustrated for two monophase thin ...
