    • Proper general decomposition (PGD) for the resolution of Navier–Stokes equations 
      Article dans une revue avec comité de lecture
      DUMON, Antoine; ALLERY, Cyrille; ccAMMAR, Amine (Elsevier, 2011)
      In this work, the PGD method will be considered for solving some problems of fluid mechanics by looking for the solution as a sum of tensor product functions. In the first stage, the equations of Stokes and Burgers will ...
    • Numerical simulation and experimental study of thrust air bearings with multiple orifices 
      Article dans une revue avec comité de lecture
      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 ...
    • Oxidation induced changes in viscoelastic properties of a thermostable epoxy matrix 
      Article dans une revue avec comité de lecture
      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 ...
    • Space–time proper generalized decompositions for the resolution of transient elastodynamic models 
      Article dans une revue avec comité de lecture
      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 ...
    • One and two-fiber orientation kinetic theories of fiber suspensions 
      Article dans une revue avec comité de lecture
      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 ...
    • An overview of the proper generalized decomposition with applications in computational rheology 
      Article dans une revue avec comité de lecture
      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 ...
    • Proper generalized decomposition of time-multiscale models 
      Article dans une revue avec comité de lecture
      ccAMMAR, Amine; ccCHINESTA SORIA, Francisco; ccCUETO, Elias; DOBLARÉ, Manuel (Wiley, 2012)
      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 ...
