    • A multiscale separated representation to compute the mechanical behavior of composites with periodic microstructure 
      Article dans une revue avec comité de lecture
      METOUI, Sondes; ccPRULIERE, Etienne; ccAMMAR, Amine; ccDAU, Frédéric; ccIORDANOFF, Ivan (Elsevier, 2018)
      The requirements for advanced numerical computations are very high when studying the multiscale behavior of heterogeneous structures such as composites. For the description of local phenomena taking place on the microscopic ...
    • Numerical investigations on a yarn structure at the microscale towards scale transition 
      Article dans une revue avec comité de lecture
      DEL SORBO, Pietro; ccGIRARDOT, Jeremie; ccDAU, Frédéric; ccIORDANOFF, Ivan (Elsevier, 2017)
      Since the beginning of the last decade, few examples of multifilament models for dry fabrics have been presented in literature. This work deals with the simulation of a single yarn subjected to transverse impact. Inspired ...
    • A reduced model to simulate the damage in composite laminates under low velocity impact 
      Article dans une revue avec comité de lecture
      METOUI, Sondes; ccPRULIERE, Etienne; ccAMMAR, Amine; ccDAU, Frédéric (Elsevier, 2018)
      This article presents an efficient numerical strategy to simulate the damage in composite laminates under low velocity impact. The proposed method is based on a separated representation of the solution in the context of ...
    • On the solution of the heat equation in very thin tapes 
      Article dans une revue avec comité de lecture
      ccPRULIERE, Etienne; ccCHINESTA SORIA, Francisco; ccAMMAR, Amine; LEYGUE, Adrien; POITOU, Arnaud (Elsevier, 2012)
      This paper addresses two issues usually encountered when simulating thermal processes in forming processes involving tape-type geometries, as is the case of tape or tow placement, surface treatments, / The first issue ...
    • Imperfection-sensitive ductility of aluminium thin films 
      Article dans une revue avec comité de lecture
      COULOMBIER, Marc; BOE, Alexandre; RASKIN, Jean.Pierre; PARDOEN, Therry; ccBRUGGER, Charles (Elsevier, 2010)
      Ductility, defined as the strain at the onset of necking, has been characterized in thin Al films using an on-chip, internal stress actuated, microtensile testing setup. In the smallest specimens, the ductility is equal ...
    • Fatigue damage mechanisms of short fiber reinforced PA66 as observed by in-situ synchrotron X-ray microtomography 
      Article dans une revue avec comité de lecture
      ROLLAND, Héloise; ccSAINTIER, Nicolas; RAPHAEL, Ilan; LENOIR, Nicolas; KING, Andrew; ROBERT, Gilles (Elsevier, 2018)
      The understanding of fatigue damage mechanisms of short fiber reinforced thermoplastics are a key issue in order to optimize material processing and propose physically based multiscale fatigue damage models. The presented ...
    • Effect of defect size and shape on the high-cycle fatigue behavior 
      Article dans une revue avec comité de lecture
      GUERCHAIS, Raphaël; ccMOREL, Franck; ccSAINTIER, Nicolas (Elsevier, 2017)
      This study aims to examine the effects of both material microstructure and voids on the high-cycle fatigue behavior of metals. To deal with this matter, finite element analyses of polycrystalline aggregates are carried ...
