      CHARKI, Abdérafi; DIOP, Khadim; ccCHAMPMARTIN, Stephane; AMBARI, Abdelhak (Elsevier, 2013)
      The objective of this paper is to provide a numerical simulation and an experimental study in order to assess stiffness and damping characteristics of thrust air bearings with multiple orifices. Finite element modeling is ...

      MILLE, Marion; ccFAYOLLE, Bruno; ccCOLIN, Xavier; ccTEREKHINA, Svetlana (Wiley, 2013)
      The thermal ageing of a neat epoxy matrix has been studied at 200°C in air by three complementary analytical techniques: optical microscopy, mechanical spectrometry and nano-indentation. Thermal oxidation is restricted in ...

      BOUCINHA, Lucas; GRAVOUIL, Anthony; ccAMMAR, Amine (Elsevier, 2013)
      In this paper, we investigate ability of proper generalized decomposition (PGD) to solve transient elastodynamic models in space–time domain. Classical methods use time integration schemes and an incremental resolution ...

      GRMELA, Miroslav; ccAMMAR, Amine; ccCHINESTA SORIA, Francisco (Elsevier, 2013)
      The morphology influencing rheological properties of suspensions of rigid spheres constitutes the flow induced collective ordering of the spheres characterized by two or more sphere distribution functions. When the rigid ...

      ccCHINESTA SORIA, Francisco; ccAMMAR, Amine; LEYGUE, Adrien; KEUNINGS, Roland (Elsevier, 2011)
      We review the foundations and applications of the proper generalized decomposition (PGD), a powerful model reduction technique that computes a priori by means of successive enrichment a separated representation of the ...

      Models encountered in computational mechanics could involve many time scales. When these time scales cannot be separated, one must solve the evolution model in the entire time interval by using the finest time step that ...

      DESPEYROUX, Antoine; AMBARI, Abdelhak; BEN RICHOU, Abderrahim (Elsevier, 2011)
      The present work deals with the numerical calculation of the Stokes-type drag undergone by a cylindrical particle perpendicularly to its axis in a power-law fluid. In unbounded medium, as all data are not available yet, ...
