    • 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 ...
    • Impact of microstructural mechanisms on ductility limits 
      Communication avec acte
      FRANZ, Gérald; ccABED-MERAIM, Farid; BEN ZINEB, Tarak; LEMOINE, Xavier; BERVEILLER, Marcel (2011)
      In order to investigate the effects of microstructure and deformation mechanisms on the ductility of multiphase steels, a formability criterion based on loss of ellipticity of the boundary value problem is coupled with an ...
    • New quadratic solid-shell elements and their evaluation on popular benchmark problems 
      Communication sans acte
      ccABED-MERAIM, Farid; TRINH, Vuong-Dieu; COMBESCURE, Alain (Pavel Solin, Pavel Karban, Jaroslav Kruis, 2012)
      In recent years, considerable effort has been devoted to the development of 3D finite elements able to model thin structures (Cho et al., 1998; Sze and Yao, 2000; Abed-Meraim and Combescure, 2002; Vu-Quoc and Tan, 2003; ...
    • Interaction of bone-dental implant with new ultra low modulus alloy using a numerical approach 
      Article dans une revue avec comité de lecture
      PIOTROWSKI, Boris; BAPTISTA, André; PATOOR, Etienne; BRAVETTI, Pierre; EBERHARDT, André; LAHEURTE, Pascal (Elsevier, 2014)
      Although mechanical stress is known as being a significant factor in bone remodeling, most implants are still made using materials that have a higher elastic stiffness than that of bones. Load transfer between the implant ...
    • Influence of temperature on stress distribution in bainitic steels -Application to 16MND5-A508 pressure vessel steel 
      Article dans une revue avec comité de lecture
      OUAHAB, Razane; PATOOR, Etienne; ccBERVEILLER, Sophie; ccPESCI, Raphaël (Trans Tech Publications Inc, 2011)
      In this study, the internal stress evolution of the ferrite phase of 16MND5-A508 has been determined using X-Ray Diffraction (XRD). The results of in situ tests combined with XRD analyses and performed at different ...
    • Implicit implementation and consistent tangent modulus of a viscoplastic model for polymers 
      Article dans une revue avec comité de lecture
      ACHOUR-RENAULT, Nadia; CHATZIGEORGIOU, George; ccMERAGHNI, Fodil; CHEMISKY, Yves; ccFITOUSSI, Joseph (Elsevier, 2015)
      In this work, the phenomenological viscoplastic DSGZ model[Duan, Y., Saigal, A., Greif, R., Zimmerman, M. A., 2001. A Uniform Phenomenological Constitutive Model for Glassy and Semicrystalline Polymers. Polymer Engineering ...
    • Effect of projectile nose shape on ballistic resistance of interstitial-free steel sheets 
      Article dans une revue avec comité de lecture
      KPENYIGBA, K. M.; JANKOWIAK, Tomasz; RUSINEK, Alexis; WANG, Bin; ccPESCI, Raphaël (Elsevier, 2015)
      In this paper an experimental and numerical work is reported concerning the process of perforation of thin steel plates using different projectile nose shapes. The main goal is to analyze how the projectile shape may change ...
