    • A physically stabilized and locking-free formulation of the (SHB8PS) solid-shell element 
      Article dans une revue avec comité de lecture
      ccABED-MERAIM, Farid; COMBESCURE, Alain (Hermès / Paris : Lavoisier, 2007)
      In this work, the formulation of the SHB8PS finite element is reviewed in order to eliminate some persistent membrane and shear locking phenomena. This is a solid-shell element based on a purely three-dimensional formulation. ...
    • Micromechanics-Based Damage Analysis of Fracture in Ti5553 Alloy with Application to Bolted Sectors 
      Article dans une revue avec comité de lecture
      ccBEN BETTAIEB, Mohamed; VAN HOOF, Thibaut; MINNEBO, Hans; PARDOEN, Thomas; DUFOUR, Philippe; JACQUES, Pascal J.; HABRAKEN, Anne-Marie (Springer Verlag/ASM International, 2015)
      A physics-based, uncoupled damage model is calibrated using cylindrical notched round tensile specimens made of Ti5553 and Ti-6Al-4V alloys. The fracture strain of Ti5553 is lower than for Ti-6Al-4V in the full range of ...
    • Investigation and modeling of the fatigue damage in natural fiber composites 
      Conférence invitée
      BOUGHERARA, Habiba; EL SAWI, Ihab; FAWAZ, Zouheir; ccMERAGHNI, Fodil (Ibrahim Karaman, Raymundo Arróyave and Eyad Masad, 2015)
      The main objective of this preliminary investigation is to identify and characterize the damage evolution of angle ply ([±45] 16 ) flax-reinforced epoxy composites using an energy-based damage model combined with Scanning ...
    • Extended infrared thermography applied to orthogonal cutting 
      Article dans une revue avec comité de lecture
      ARTOZOUL, Julien; BOMONT, Olivier; DUDZINSKI, Daniel; ccLESCALIER, Christophe (Elsevier, 2014)
      The temperature knowledge is essential to understand and model the phenomena involved in metal cutting. A global measured value can only provide a clue of the heat generation during the process; however the deep understanding ...
    • Micromechanics modeling of magneto-sensitive polymeric materials during curing 
      Conférence invitée
      CHATZIGEORGIOU, George; HOSSAIN, Mokarram; ccMERAGHNI, Fodil; STEINMANN, Paul (2015)
      This work proposes a coupled magneto-mechanical multi-scale model for simulating the curing process of magneto-sensitive polymers. In this type of composites, ferromagnetic particles are mixed with a liquid polymeric matrix ...
    • New prismatic solid-shell element : Assumed strain formulation and hourglass mode analysis 
      Article dans une revue avec comité de lecture
      ccABED-MERAIM, Farid; COMBESCURE, Alain (Techno-press Ltd, 2011)
      The formulation of a six-node solid-shell called SHB6, which is a linear, isoparametric element, is discussed. An eigenvalue analysis of the element stiffness matrix is first carried out. Several modifications are introduced ...
    • Size Effects in a Silica-Polystyrene Nanocomposite: Molecular Dynamics and Surface-enhanced Continuum Approaches 
      Article dans une revue avec comité de lecture
      DAVYDOV, Denis; VOYIATZIS, Evangelos; CHATZIGEORGIOU, George; LIU, Shengyuan; STEINMANN, Paul; BOHM, Michael C.; MULLER-PLATHE, Florian (Taylor & Francis, 2014)
      Size effects in a system composed of a polymer matrix with a single silica nanoparticle are studied using molecular dynamics and surface-enhanced continuum approaches. The dependence of the composite’s mechanical properties ...
