    • Numerical investigation of necking in perforated sheets using the periodic homogenization approach 
      Article dans une revue avec comité de lecture
      ZHU, Jianchang; ccBEN BETTAIEB, Mohamed; ccABED-MERAIM, Farid  (Elsevier, 2020)
      Due to their attractive properties, perforated sheets are increasingly used in a number of industrial applications, such as automotive, architecture, pollution control, etc. Consequently, the accurate modeling of the ...
    • Architectural effect on 3D elastic properties and anisotropy of cubic lattice structures 
      Article dans une revue avec comité de lecture
      LOHMULLER, Paul; FAVRE, Julien; KENZARI, Samuel; PIOTROWSKI, Boris; PELTIER, Laurent; LAHEURTE, Pascal (Elsevier, 2019)
      This article investigates the elastic properties of a large panel of lattice architectures using a continuous description of geometry. The elastic constants of the orthotropic material are determined, and discussed in terms ...
    • Numerical tool for SMA material simulation: application to composite structure design 
      Article dans une revue avec comité de lecture
      CHEMISKY, Yves; DUVAL, Arnaud; PIOTROWSKI, Boris; BEN ZINEB, Tarak; TAHIRI, Vanessa; PATOOR, Etienne (IOP Publishing, 2009)
      Composite materials based on shape memory alloys (SMA) have received growing attention over these last few years. In this paper, two particular morphologies of composites are studied. The first one is an SMA/elastomer ...
    • Homogenization accounting for size effects in particulate composites due to general interfaces 
      Article dans une revue avec comité de lecture
      FIROOZ, Soheil; CHATZIGEORGIOU, George; MERAGHNI, Fodil; JAVILI, Ali (Elsevier, 2019)
      Two analytical approaches are developed to determine the overall size-dependent response of composites embedding general interfaces. The first approach extends the composite sphere assemblage (CSA) approach and the generalized ...
    • Metallurgical Analysis of Chip Forming Process when Machining High Strength Bainitic Steels 
      Article dans une revue avec comité de lecture
      HADDAD, Fares; DESAIGUES, Jean-Edouard; BOMONT-ARZUR, Anne; BOMONT, Olivier; ccLESCALIER, Christophe (MDPI, 2019)
      In the following work, we propose a metallurgical approach to the chip formation process. We focus on a turning application of high strength steel in which chips are produced by adiabatic shear bands that generate cutting ...
    • Elastic and inelastic local strain fields in composites with coated fibers or particles: theory and validation 
      Article dans une revue avec comité de lecture
      CHATZIGEORGIOU, George; MERAGHNI, Fodil (SAGE Publications, 2019)
      This paper deals with mean field multiscale approaches for coated fiber- or particle-reinforced composites under nonlinear strain. The current work attempts to extend Dvorak’s well-known transformation field analysis for ...
    • A systematic study on homogenization and the utility of circular simplified RVE 
      Article dans une revue avec comité de lecture
      FIROOZ, Soheil; SAEB, Saba; CHATZIGEORGIOU, George; MERAGHNI, Fodil; STEINMANN, Paul; JAVILI, Ali (SAGE Publications, 2019)
      Although both computational and analytical homogenization are well-established today, a thorough and systematic study to compare them is missing in the literature. This manuscript aims to provide an exhaustive comparison ...
