    • Pantographic metamaterials: A view towards applications 
      Article dans une revue avec comité de lecture
      DELL'ISOLA, Francesco; GIORGIO, Ivan; PLACIDI, Luca; SPAGNUOLO, Mario; PEYRE, Patrice; DUPUY, Corinne; DIRRENBERGER, Justin; PAWLIKOWSKI, M; IGUMNOV, Leonid A. (Institute of Problems of Mechanical Engineering, 2019)
      The purpose of this article is to show the basic characteristics of the so-called pantographic metamaterial. Here we underline how the microstructure provides some exotic properties and, in principle, implies the second ...
    • Ab-Initio Calculations 
      Chapitre d'ouvrage scientifique
      ccABISSET-CHAVANNE, Emmanuelle; ccCHINESTA SORIA, Francisco (Springer, 2018)
      Due to the difficulties found in the direct solution of the Schrödinger equation, different simplified approaches were proposed and are nowadays widely used. Among them, those most usually employed are the Hartree–Fock and ...
    • Depth dependence and keyhole stability at threshold, for different laser welding regimes 
      Article dans une revue avec comité de lecture
      FABBRO, Remy (MDPI, 2020)
      Depending of the laser operating parameters, several characteristic regimes of laser welding can be observed. At low welding speeds, the aspect ratio of the keyhole can be rather large with a rather vertical cylindrical ...
    • Mechanical properties of thermally sprayed porous alumina coating by Vickers and Knoop indentation 
      Article dans une revue avec comité de lecture
      BEN GHORBAL, Ghailen; TRICOTEAUX, Arnaud; THUAULT, Anthony; AGEORGES, Hélène; ROUDET, Francine; CHICOT, Didier (Elsevier, 2020)
      Depending on the thermal spraying conditions, coatings obtained can present different defects, like pores, cracks and/or unmelted particles, and different surface roughnesses, that can affect the determination of the ...
    • Microstructure-mechanical properties relationships in vibration welded glass-fiber-reinforced polyamide 66: A high-resolution X-ray microtomography study 
      Article dans une revue avec comité de lecture
      MOFAKHAMI, Eeva; TENCÉ-GIRAULT, Sylvie; PERRIN, Jonathan; SCHEEL, Mario; GERVAT, Laurent; OVALLE RODAS, Cristian; LAIARINANDRASANA, Lucien; MIQUELARD-GARNIER, Guillaume; ccFAYOLLE, Bruno (Elsevier, 2020)
      The effect of initial fiber orientation and welding conditions on the mechanical properties and microstructure of 30 wt% glass-fiber-reinforced polyamide 66 was systematically evaluated. For all conditions studied no ...
    • Modeling the visco-hyperelastic–viscoplastic behavior of photodegraded semi-crystalline low-density polyethylene films 
      Article dans une revue avec comité de lecture
      AYOUB, Georges; RODRIGUEZ, A.K.; MANSOOR, B.; ccCOLIN, Xavier (Elsevier, 2020)
      In this work we propose to model the mechanical and fracture response of semi-crystalline low-density polyethylene (LDPE) films exposed to accelerated ultraviolet (UV) ageing using a physically based visco-hyperelastic–v ...
    • About the heat sources generated during fatigue crack growth: What consequences on the stress intensity factor? 
      Article dans une revue avec comité de lecture
      BOUSSATTINE, Zaid; ccPALIN-LUC, Thierry; ccRANC, Nicolas (Elsevier, 2020)
      During cyclic loading of a cracked metallic alloy at room temperature, heat sources are generated and produce a heterogeneous temperature field around the crack tip. Those heat sources are: (i) the thermo-elastic coupling ...
