    • Harmonic Balance-Based Approach for Quasi-Periodic Motions and Stability Analysis 
      Article dans une revue avec comité de lecture
      THOUVEREZ, Fabrice; ccGUSKOV, Mikhail (American Society of Mechanical Engineers, 2012)
      Quasi-periodic motions and their stability are addressed from the point of view of different harmonic balance-based approaches. Two numerical methods are used: a generalized multidimensional version of harmonic balance and ...
    • Explanation of penetration depth variation during laser welding under variable ambient pressure 
      Article dans une revue avec comité de lecture
      PANG, Shengyong; HIRANO, Koji; FABBRO, Rémy; JIANG, Tao (Laser Institute of America, 2015)
      It has been observed that the penetration depth during laser welding (LW) under vacuum or reduced ambient pressure could be significantly greater than that during welding under atmospheric pressure. Previous explanations ...
    • Yb–YAG laser offset welding of AA5754 and T40 butt joint 
      Article dans une revue avec comité de lecture
      CASALINO, Giuseppe; MORTELLO, Michelangelo; PEYRE, Patrice (Elsevier, 2015)
      In this work, a 5754 Al alloy and T40 were joined in butt configuration by focusing a fiber laser onto the titanium side, close to the weld centerline (offset). The keyhole was made entirely of titanium, and the fusion of ...
    • Micromechanical modelling of twinning-induced plasticity steels 
      Article dans une revue avec comité de lecture
      BARBIER, D; ccFAVIER, Véronique (Elsevier, 2012)
      The paper discusses a number of issues related to the development of a micromechanical polycrystalline model for twinning-induced plasticity steels: twinning features that have to be incorporated, identification procedure, ...
    • Fatigue Damage Initiation of a PA66/Glass Fibers Composite Material 
      Article dans une revue avec comité de lecture
      ESMAEILLOU, Bardia; FEREIRRA, P; BELLENGER, Véronique; ccTCHARKHTCHI, Abbas (Wiley, 2012)
      Fatigue damage initiation of a PA66/glass fiber composite material is studied with interrupted tests carried out with an “alternative bending device” and a small applied strain. During the damage initiation period, no ...
    • Non-incremental transient solution of the Rayleigh–Bénard convection model by using the PGD 
      Article dans une revue avec comité de lecture
      AGHIGHI, Mohammad Saeid; ccAMMAR, Amine; METIVIER, Christel; NORMANDIN, Magdeleine; ccCHINESTA SORIA, Francisco (Elsevier, 2013)
      This paper focuses on the non-incremental solution of transient coupled non-linear models, in particular the one related to the Rayleigh–Bénard flow problem that models natural thermal convection. For this purpose we are ...
    • The influence of constitutive material models on accumulated plastic strain in finite element weld analyses 
      Article dans une revue avec comité de lecture
      MURÁNSKY, O; HAMELIN, C.J.; PATEL, V.I; LUZIN, V; ccBRAHAM, Chedly (Elsevier, 2015)
      Recent studies in computational weld mechanics have revealed the importance of the material plasticity model when predicting weld residual stresses. The present work seeks to extend this level of understanding to include ...
