    • Investigation of thick sheet AHSS springback in combined bending under tension 
      Article dans une revue avec comité de lecture
      RACZ, Sever-Gabriel; ccCHALAL, Hocine; ccBALAN, Tudor (Trans Tech Publications, 2012)
      In this paper, we investigate the springback behavior of several advanced high-strength sheet steels (TRIP, Dual-Phase, ferrite-bainite) with thicknesses up to 4 mm. Samples were tested by means of the bending-under-tension ...
    • A new assumed strain solid-shell formulation "SHB6" for the six-node prismatic finite element 
      Article dans une revue avec comité de lecture
      TRINH, Vuong-Dieu; COMBESCURE, Alain; ccABED-MERAIM, Farid  (Springer, 2011)
      This paper presents the development of a new prismatic solid-shell finite element, denoted SHB6, obtained using a purely three-dimensional approach. This element has six nodes with displacements as the only degrees of ...
    • A proposed set of popular limit-point buckling benchmark problems 
      Article dans une revue avec comité de lecture
      LEAHU-ALUAS, Ion; ccABED-MERAIM, Farid  (Techno-press Ltd, 2011)
      Developers of new finite elements or nonlinear solution techniques rely on discriminative benchmark tests drawn from the literature to assess the advantages and drawbacks of new formulations. Buckling benchmark tests provide ...
    • New quadratic solid-shell elements and their evaluation on linear benchmark problems 
      Article dans une revue avec comité de lecture
      TRINH, Vuong-Dieu; COMBESCURE, Alain; ccABED-MERAIM, Farid  (Springer Verlag, 2013)
      This paper is concerned with the development of a new family of solid- shell finite elements. This concept of solid-shell elements is shown to have a number of attractive computational properties as compared to conventional ...
    • Impact of intragranular substructure parameters on the forming limit diagrams of single-phase B.C.C. steels 
      Article dans une revue avec comité de lecture
      FRANZ, Gérald; BERVEILLER, Marcel; ccABED-MERAIM, Farid  (MDPI, 2013)
      An advanced elastic-plastic self-consistent polycrystalline model, accounting for intragranular microstructure development and evolution, is coupled with a bifurcation-based localization criterion and applied to the numerical ...
    • Impact of intragranular microstructure development on ductility limits of multiphase steels 
      Article dans une revue avec comité de lecture
      FRANZ, Gérald; BEN ZINEB, Tarak; LEMOINE, Xavier; BERVEILLER, Marcel; ccABED-MERAIM, Farid  (Elsevier, 2011)
      In this paper, the effects of microstructure and deformation mechanisms on the ductility of multiphase steels are investigated. To this end, a formability criterion based on loss of ellipticity of the boundary value problem ...
    • Effect of microstructural and physical mechanisms on mechanical properties of single-phase steels 
      Article dans une revue avec comité de lecture
      FRANZ, Gérald; BEN ZINEB, Tarak; ccABED-MERAIM, Farid  (American Scientific Publishers, 2013)
      The current work aims to investigate the impact of microstructural and physical mechanisms on the macroscopic behavior and ductility of single-phase steels. For this purpose, an advanced multiscale model, accounting for ...
