    • Influence of SLM process parameters on the surface finish, porosity rate and fatigue behavior of as-built Inconel 625 parts 
      Article dans une revue avec comité de lecture
      PEYRE, Patrice; AMLOU, Ouafae; DE TERRIS, Thibaut; ccKOUTIRI, Imade; ccPESSARD, Etienne (Elsevier, 2018)
      This paper is dedicated to understanding fatigue crack initiation for an Inconel 625 manufactured by SLM, using a hatching + contour procedure. In the first part of the paper, an optimum set of parameters was found to ...
    • EBSD-assisted Laue microdiffraction for microstrain analysis 
      Article dans une revue avec comité de lecture
      ÖRS, Taylan; MICHA, Jean-Sébastien; GEY, Nathalie; MICHEL, Vincent; CASTELNAU, Olivier; GUINEBRETIERE, René (International Union of Crystallography, 2018)
      The X-ray Laue microdiffraction (mLaue) technique has been establishing itself as a reliable means for microstrain analysis for the past few decades. One problem with this technique is that when the crystal size is ...
    • In-situ experimental and numerical studies of the damage evolution and fracture in a Fe-TiB2 composite 
      Article dans une revue avec comité de lecture
      HADJEM-HAMOUCHE, Z.; HÉRIPRÉ, E.; CHEVALIER, Jean-Pierre; ccDERRIEN, Katell (Elsevier, 2018)
      A joint experimental and modelling study of plastic strain and ensuing damage in a novel metal matrix composite (Fe-TiB2) is presented. Damage is observed and quantified using SEM images processing and Acoustic Emission ...
    • Role of Charge of Micellar Worms in Modulating Structure and Rheological Properties of Their Mixtures with Nonionic Polymer 
      Article dans une revue avec comité de lecture
      SHIBAEV, Andrey V.; MAKAROV, Anton V.; KUKLIN, Alexander I.; LIOPOULOS, Ilias; PHILIPPOVA, Olga E. (American Chemical Society, 2018)
      The paper describes phase behavior, microstructure, and rheological properties of the mixtures of surfactant micelles of varying negative charge with nonionic hydrophilic polymer poly(vinyl alcohol) (PVA) weakly interacting ...
    • Fast fatigue life prediction of short fiber reinforced composites using a new hybrid damage approach: Application to SMC 
      Article dans une revue avec comité de lecture
      LARIBI, Mohamad-Amine; TAMBOURA, Sahbi; BEN DALI, Hachmi; ccTCHARKHTCHI, Abbas; ccFITOUSSI, Joseph (Elsevier, 2018)
      Industrial design of Short Fiber Reinforced Composites (SFRC) structures is subject to several compounding and processing steps of optimization. Moreover, these structures are often submitted to fatigue loading. Therefore, ...
    • Evidence of 3D strain gradients associated with tin whisker growth 
      Article dans une revue avec comité de lecture
      HEKTOR, Johan; MARIJON, Jean-Baptiste; RISTINMAA, Matti; HALL, Stephen A.; HALLBERG, Hakan; SRINIVASAN, Iyengar; MICHA, Jean-Sébastien; ROBACH, Odile; GRENNERAT, Fanny; CASTELNAU, Olivier (Elsevier, 2018)
      We have used Differential Aperture X-ray Microscopy (DAXM) to measure grain orientations and deviatoric elastic strains in 3D around a tin whisker. The results show strain gradients through the depth of the tin coating, ...
    • Multi-scale and multi-technique analysis of the thermal degradation of poly(ether ether ketone) 
      Article dans une revue avec comité de lecture
      COURVOISIER, Emilie; BICABA, Yoann; ccCOLIN, Xavier (Elsevier, 2018)
      The thermal degradation of PEEK has been studied in rubbery state in wide ranges of temperature (between 180 and 320 °C) and oxygen partial pressure (between 0.21 and 50 bars). On one hand, the thermal ageing mechanisms ...
