    • Estimation of stress in specimens loaded with ultrasonic fatigue machines 
      Article dans une revue avec comité de lecture
      JACQUEMAIN, Vincent; CHEULEU, Christophe; MICHEL, Vincent; CASTELNAU, Olivier; VINCI, Doriana; THIAUDIERE, Dominique; MOCUTA, Christian; ccRANC, Nicolas; ccFAVIER, Véronique (Elsevier BV, 2021)
      Piezo-electric ultrasonic fatigue machines are used to carry out fatigue tests more rapidly than what is possible using other technologies, at a frequency of . The very high cycle fatigue (VHCF) domain can be studied with ...
    • Absorptivity measurements during laser powder bed fusion of pure copper with a 1 kW cw green laser 
      Article dans une revue avec comité de lecture
      NORDET, G.; GORNY, C.; MAYI, Y.; DALIGAULT, J.; ccDAL, Morgan; EFFERNELLI, A.; BLANCHET, E.; ccCOSTE, FREDERIC; ccPEYRE, Patrice (Elsevier, 2022)
      A 1 kW CW green laser source operating at 515 nm was used to investigate the absorptivity of pure copper powder beds and pure copper substrates. Various interaction regimes were considered, ranging from the solid and/or ...
    • Multi scale aging assessment of low-voltage cables subjected to radio-chemical aging: Towards an electrical diagnostic technique 
      Article dans une revue avec comité de lecture
      SURACI, Simone Vincenzo; FABIANI, Davide; ccCOLIN, Xavier; ccROLAND, Sébastien (Elsevier BV, 2021)
      In this article, the aging behavior of nuclear-grade low voltage cables, characterized by different geometries and insulation compositions, is investigated. Cables were subjected to radio-chemical aging at different dose ...
    • Experimental and numerical analysis of the energy efficiency of PCM concrete wallboards under different thermal scenarios 
      Article dans une revue avec comité de lecture
      ESSID, Nessrine; EDDHAHAK, Anissa; NEJI, Jamel (Elsevier BV, 2022)
      This paper aims to investigate the energy efficiency of PCM-concrete wallboards using experimental and numerical approaches. First, a laboratory experimental work was performed to manufacture PCM-concrete mixtures with ...
    • A unified mechanical based approach to fracture properties estimates of rubbers subjected to aging 
      Article dans une revue avec comité de lecture
      KADRI, Réda; NAIT ABDELAZIZ, Moussa; BEN HASSINE, Moussa; WITZ, Jean-François; ccFAYOLLE, Bruno (Elsevier BV, 2021)
      In this work, the influence of aging on the mechanical properties at break of rubber materials are examined. When subjected to physical-chemical aging, the structure of the rubber network is deeply modified through two ...
    • Experiments and Simulations of Free-Surface Flow behind a Finite Height Rigid Vertical Cylinder 
      Article dans une revue avec comité de lecture
      AGEORGES, Valentin; PEIXINHO, Jorge; PERRET, Gaële; LARTIGUE, Ghislain; MOUREAU, Vincent (MDPI AG, 2021)
      We present the results of a combined experimental and numerical study of the free-surface flow behind a finite height rigid vertical cylinder. The experiments measure the drag and the wake angle on cylinders of different ...
    • Dewetting of a thin polymer film under shear 
      Article dans une revue avec comité de lecture
      KADRI, Kheireddin; PEIXINHO, Jorge; SALEZ, Thomas; MIQUELARD-GARNIER, Guillaume; SOLLOGOUB, Cyrille (Elsevier BV, 2021)
      The objective of this work is to give new insight into the stability of thin polymer films under shear, in order to pave the way to a better control of the nanolayer coextrusion process. To do so, a finite-difference ...
