    • Finite element simulation of deep drawing with initial and induced anisotropy 
      Communication avec acte
      ccBALAN, Tudor; ccABED-MERAIM, Farid; ccHADDAG, Badis (2004-05)
      Deep drawing is a forming process widely used to obtain parts of suited shape from sheets initially flat. These sheets are obtained generally by rolling and thus present an initial orthotropic anisotropy. Several behaviour ...
    • Numerical predictions of ductile fracture limits in deep drawing processes 
      Communication avec acte
      ccCHALAL, Hocine; ccABED-MERAIM, Farid (Luso Impress S.A. Publisher, 2015)
      In this work, two numerical ductile fracture criteria based on finite element (FE) simulations are proposed for the prediction of ductile fracture limits (DFLs) for sheet metals. An elastic–plastic model coupled with the ...
    • SHB8PS––a new adaptive, assumed-strain continuum mechanics shell element for impact analysis 
      Article dans une revue avec comité de lecture
      ccABED-MERAIM, Farid; COMBESCURE, Alain (Elsevier BV, 2002-04)
      This paper presents the formulation of a new adaptive shell element. This is an eight-node brick element in which one chooses a special direction denoted ‘‘thickness’’. The element is an assumed-strain element based on the ...
    • Impact of morphological and crystallographic textures on the formability limits of thin metal sheets using a CPFEM-based approach 
      Communication avec acte
      ZHOU, Shuai; ccBEN BETTAIEB, Mohamed; ccABED-MERAIM, Farid (2024-05-13)
      The objective of this contribution is to investigate the influence of morphological and crystallographic textures on the formability limits of polycrystalline aggregates using the Crystal Plasticity Finite Element Method ...
    • Springback Simulation: Impact of Some Advanced Constitutive Models and Numerical Parameters 
      Communication avec acte
      ccHADDAG, Badis; ccBALAN, Tudor; ccABED-MERAIM, Farid (Smith, LM; Pourboghrat, F; Yoon, JW; Stoughton, TB, 2005-08)
      The impact of material models on the numerical simulation of springback is investigated. The study is focused on the strain-path sensitivity of two hardening models. While both models predict the Bauschinger effect, their ...
    • Wabi-Sabi in Virtual Reality Sketching: Toward a Digital Creator’s Posture Change 
      Article dans une revue avec comité de lecture
      HENRY, Gaëtan; JÉGO, Jean-François; ccFLEURY, Sylvain; GUEZ, Judith; SEDDOH, Rachel; CHEN, Chu-Yin; ccRICHIR, Simon (MIT Press, 2025-06-01)
      Traditional design promotes abundant, inexpensive, and disposable ways to create that are not compatible with sustainability. The authors explore alternatives to this paradigm by comparing a virtual reality sketch method ...
    • Ductility Loss Modelling for BCC single Crystals 
      Article dans une revue avec comité de lecture
      LORRAIN, Jean-Paul; ccBEN ZINEB, Tarak; ccABED-MERAIM, Farid; BERVEILLER, Marcel (Hermes Science Publications, 2005-08)
      An elastic-plastic micromechanical behavior model written in the finite strains framework is presented. It is shown that the present model is able to reproduce the behavior for BCC materials during simple and complex loading ...
