    • Rotational Molding of Polyamide-12 Nanocomposites: Modeling of the Viscoelastic Behavior 
      Article dans une revue avec comité de lecture
      SHIRINBAYAN, Mohammadali; MONTAZERI, A.; NOURI SEDEH, M.; ABBASNEZHAD, Navideh; ccTCHARKHTCHI, Abbas; ccFITOUSSI, Joseph (Springer Verlag, 2021)
      Nowadays, polyamide 12 (PA-12) is considered as an interesting polymer in the rotomolding process to manufacture different pieces like the liner part in the storage hydrogen tank (type IV). In this study, the pure polyamide-12 ...
    • Physico-chemical approach of polymer chemical ageing: a short review 
      Article dans une revue avec comité de lecture
      ccRICHAUD, Emmanuel (Elsevier Masson, 2021)
      Polymers are known to degrade in their use conditions, with the risk that their properties reach unacceptable level. This paper reviews the modeling of modifications occurring at molecular and architectural changes occurring ...
    • ROMP of novel hindered phenol-functionalized norbornenes and preliminary evaluation as stabilizing agents† 
      Article dans une revue avec comité de lecture
      NICOLAS, Clémence; HUANG, Jing; MINNE, Wendy; DROZDZAK, Renata; RECHER, Gilles; FONTAINE, Laurent; MONTEMBAULT, Véronique; ccRICHAUD, Emmanuel (Elsevier, 2021)
      A series of new norbornene monomers containing sterically hindered phenol groups have been synthesized and polymerized via ring-opening metathesis polymerization (ROMP) using the Grubbs 3rd generation catalyst (G3’). ROMPs ...
    • Periodic smoothing splines for FFT-based solvers 
      Article dans une revue avec comité de lecture
      MORIN, Léo; BRENNER, Renald; DORHMI, Khaoula; ccDERRIEN, Katell (Elsevier, 2021)
      The aim of this paper is to develop a periodic smoother based on splines for FFT-based solvers. Spurious oscillations in FFT-based methods are shown to be due to pseudo-spectral differentiation of discontinuous fields. An ...
    • Evolution of mechanical properties of aged poly(ether ketone ketone) explained by a microstructural approach 
      Article dans une revue avec comité de lecture
      MOGHADDAM, Mahdi; TENCÉ-GIRAULT, Sylvie; ccFAYOLLE, Bruno; ccROLAND, Sébastien (Elsevier, 2021)
      In this work, the thermo-oxidative behavior of PEKK films (~50 µm thick) in solid state were investigated. Since the mechanical properties of PEKK samples, especially the strain at break, are clearly affected after long ...
    • Application of electron tomography of dislocations in beam-sensitive quartz to the determination of strain components 
      Article dans une revue avec comité de lecture
      MUSSI, Alexandre; GALLET, Julien; CASTELNAU, Olivier; CORDIER, Patrick (Elsevier, 2021)
      In this study we apply electron tomography of dislocations to quartz with a view to assess whether the von Mises-Taylor criterion is satisfied or violated in a deformed crystal of quartz. We propose a method to perform ...
    • Liquid metal embrittlement of a dual-phase Al0.7CoCrFeNi high-entropy alloy exposed to oxygen-saturated lead-bismuth eutectic 
      Article dans une revue avec comité de lecture
      GONG, Xing; XIANG, Congying; AUGER, Thierry; CHEN, Jiajun; LIANG, Xiaocong; YU, Zhiyang; SHORT, Michael P; SONG, Min; YIN, Yuan (Elsevier BV, 2021)
      This paper reports a new liquid metal embrittlement (LME) system in which a dual-phase Al0.7CoCrFeNi (equimolar fraction) high-entropy alloy (HEA) is embrittled by lead-bismuth eutectic (LBE) at 350 and 500°C. At 350°C, ...
