    • Microstructure and self-heating for ferritic steels under cyclic loading at low stress magnitudes 
      Article dans une revue avec comité de lecture
      ccMAREAU, Charles; GALTIER, André; WEBER, Bastien; BERVEILLER, Marcel; ccFAVIER, Véronique (EDP Sciences, 2010)
      A newmicromechanical modelling is proposed to correlate some microstructural parameters and dissipation in ferritic steels under cyclic loading.We assumed the occurrence of two dissipative mechanisms associated with anelastic ...
    • An efficient C1 finite element with continuity requirements for multilayered/sandwich shell structures 
      Article dans une revue avec comité de lecture
      POLIT, O.; TOURATIER, Michel; ccDAU, Frédéric (Elsevier, 2004)
      This paper deals with a new triangular finite element to analyze the behaviour of multilayered shells. This element is based on a refined kinematical model and uses both conforming finite element method and higher-order ...
    • Flow and air-entrainment around partially submerged vertical cylinders 
      Article dans une revue avec comité de lecture
      AGEORGES, Valentin; PEIXINHO, Jorge; PÉRRET, Gaële (American Physical Society, 2019)
      In this study, a partially submerged vertical cylinder is moved at constant velocity through water, which is initially at rest. During the motion, the wake behind the cylinder induces free-surface deformation. Eleven ...
    • Radiation aging and chemi-crystallization processes in polyoxymethylene 
      Article dans une revue avec comité de lecture
      VERDU, Jacques; ccFAYOLLE, Bruno (Elsevier, 2011)
      The radiochemical degradation of a polyoxymethylene homopolymer (POM) was used to study the effects of molar mass changes in the crystalline structure. The dose rate was 20 kGy h -1 with doses of up to 30 kGy used. Both ...
    • Le vieillissement thermo-oxydant des polymères est-il modélisable ? 
      Article dans une revue avec comité de lecture
      AUDOUIN, Ludmila; VERDU, Jacques; ccFAYOLLE, Bruno; ccCOLIN, Xavier; ccRICHAUD, Emmanuel (EDP Sciences, 2010)
      It has been supposed, for a long time, that kinetic modelling of polymer ageing for nonempirical lifetime prediction was out of reach for two main reasons: hypercomplexity of mechanisms and heterogeneity of reactions. The ...
    • A kinetic model for predicting PET macromolecular changes during its mechanical recycling 
      Article dans une revue avec comité de lecture
      NAÏT-ALI, Linda K.; BERGERET, Anne; ccCOLIN, Xavier (EDP Sciences, 2011)
      The rheometer cavity has been used to analyse, in carefully controlled exposure conditions, the macromolecular changes generated by the mechanical recycling of PET during its extrusion. Isothermal ageing tests at 280 °C, ...
    • Modelling of thermal oxidation of phosphite stabilized polyethylene 
      Article dans une revue avec comité de lecture
      DJOUANI, Fatma; VERDU, Jacques; ccFAYOLLE, Bruno; ccRICHAUD, Emmanuel (Elsevier, 2011)
      The thermal oxidation behaviour of polyethylene films stabilized by various weight ratios of organophosphites (Irgafos 168) has been studied at selected temperatures. The duration of the induction period was found to ...
