    • Micro and macroscopic characterization of A-SMC under high speed tensile test 
      Conférence invitée
      ccSHIRINBAYAN, Mohammadali; SUROWIEC, Benjamin; BOCQUET, Michel; ccTCHARKHTCHI, Abbas; ccFITOUSSI, Joseph; ccMERAGHNI, Fodil (2015)
      Advanced Sheet Molding Compound (A-SMC) is a serious composite material candidate for structural automotive parts. It has a thermoset matrix and consists of high weight content of glass fibers (50% in mass) compared to ...
    • Combined effect of damage and plastic anisotropy on the ductility limit of thin metal sheets 
      Article dans une revue avec comité de lecture
      MSOLLI, Sabeur; ccBEN BETTAIEB, Mohamed; ccABED-MERAIM, Farid (ESIS - Elsevier, 2016)
      It is well known that both damage and plastic anisotropy strongly affect the ductility limit of thin metal sheets. Due to the manufacturing processes, initial defects, such as inclusions and voids, are ...
    • Self-consistent modelling of heterogeneous materials with an elastic-viscoplastic behavior: Application to polycrystalline agregates 
      Communication sans acte
      ccMAREAU, Charles; BERBENNI, Stéphane (Otto-von-Guericke-Universität, 2015)
      The self-consistent scheme is a common homogenization method that was developed to connect local deformation mechanisms to the overall behavior of heterogeneous disordered materials. In the past decades, many efforts have ...
    • Multi-Step Homogenization of Thermoelastic Multi-Scale Tubes with Wavy Layers 
      Conférence invitée
      TSALIS, Dimitrios; CHATZIGEORGIOU, George; CHARALAMBAKIS, Nicolas (National Technical University of Athens, 2016)
      In this paper we present a multi-step homogenization scheme of a tube made of numerous wavy cylindrical layers exhibiting periodicity with respect to both the radial and the angular direction. The proposed homogenization ...
    • Interactive learning experience in mechanics of materials: the ’SIMMIT’ project 
      Conférence invitée
      CHEMISKY, Yves; CHATZIGEORGIOU, George; ccMERAGHNI, Fodil (2016)
      This communication presents a methodology and tools that take advantage of research projects developments in the field of mechanics of materials for education outreach. Such new learning experience should meets the ...
    • On the elasto-viscoplastic behavior of the Ti5553 alloy 
      Article dans une revue avec comité de lecture
      ccBEN BETTAIEB, Mohamed; VAN HOOF, Thibaut; PARDOEN, Thomas; DUFOUR, Philippe; LENAIN, Astrid; JACQUES, Pascal J.; HABRAKEN, Anne-Marie (Elsevier, 2014)
      The elastoviscoplastic behavior of the Ti5553 alloy is characterized and compared to the classical Ti–6Al–4V alloy. The true stress–strain curves are determined based on tensile tests performed under different strain rates ...
    • Effective properties of dissipative composites under fully coupled thermomechanical processes 
      Conférence invitée
      CHATZIGEORGIOU, George; CHARALAMBAKIS, Nicolas; CHEMISKY, Yves; ccMERAGHNI, Fodil (2016)
      The current work deals with periodic composite media undergoing fully coupled thermomechanical loading. In these composites the material constituents are considered to obey the generalized standard materials laws. The aim ...
