    • MORPH-DSLAM: Model Order Reduction for Physics-Based Deformable SLAM 
      Article dans une revue avec comité de lecture
      ccBADIAS, Alberto; ALFARO, Icíar; GONZALEZ, David; ccCHINESTA SORIA, Francisco; ccCUETO, Elias (Institute of Electrical and Electronics Engineers (IEEE), 2022-11)
      We propose a new methodology to estimate the 3D displacement field of deformable objects from video sequences using standard monocular cameras. We solve in real time the complete (possibly visco-)hyperelasticity problem ...
    • Propagation of laser-generated shock waves in metals: 3D axisymmetric simulations compared to experiments 
      Article dans une revue avec comité de lecture
      CUENCA, Eduardo; ccDUCOUSSO, Mathieu; ccRONDEPIERRE, Alexandre; ccVIDEAU, Laurent; ccCUVILLIER, Nicolas; BERTHE, Laurent; ccCOULOUVRAT, François (AIP Publishing, 2020-12)
      This work aims at demonstrating the ability of an acoustic linear code to model the propagation of a shock wave created by a laser impact over a metallic surface. In this process, a high pressure surface level is reached ...
    • Bulk probing of shock wave spatial distribution in opaque solids by ultrasonic interaction 
      Article dans une revue avec comité de lecture
      ccDUCOUSSO, Mathieu; CUENCA, Eduardo; ccMARMONIER, Maxance; ccVIDEAU, Laurent; ccCOULOUVRAT, François; BERTHE, Laurent (American Physical Society (APS), 2021-05)
      We present a method to investigate the bulk propagation of a shock wave in a thick, opaque metallic plate. The shock wave is generated by laser-loading. An elastic plane probe wave, contra-propagative with respect to the ...
    • Segmental Relaxation Dynamics in Amorphous Polylactide Exposed to UV Light 
      Article dans une revue avec comité de lecture
      ccARAUJO, Steven; ccSAINLAUD, Chloé; ccDELPOUVE, Nicolas; ccRICHAUD, Emmanuel; ccDELBREILH, Laurent; ccDARGENT, Eric (Online Library Wiley, 2022-07)
      The degradation of polylactide (PLA) under UV exposure is investigated in terms of cooperativity and kinetic fragility at the glass transition. In the first part, possibly coexisting degradation mechanisms are evoked from ...
    • Elucidating the Role of Alkoxy Radicals in Polyethylene Radio-Oxidation Kinetics 
      Article dans une revue avec comité de lecture
      AHN, Yunho; ccROMA, Guido; ccCOLIN, Xavier (American Chemical Society (ACS), 2022-09)
      Polyethylene is a widely used polymer and a prototypical polyolefin. Understanding degradation mechanisms at the atomic scale leading to oxidation under the effect of temperature and/or irradiation is crucial for many ...
    • Unraveling the morphological diversity of P(VDF-ter-TrFE-ter-CTFE) semi-crystalline terpolymers via combined AFM and SAXS experiments 
      Article dans une revue avec comité de lecture
      ZANCHI, Sara; ENGEL, Marie; ccPASCAUD, Antoine; BARGAIN, François; LEBRETON, Sylvie; DOMINGUE DOS SANTOS, Fabrice; ccROLAND, Sébastien; ccTENCE-GIRAULT, Sylvie (Elsevier BV, 2023-03)
      In this article, the diverse morphologies observed after annealing or crystallization from the melt in P(VDF-ter-TrFE-ter-CTFE) terpolymers with varying CTFE amounts were explained through a combination of AFM and SAXS ...
    • Thermomechanical performance of continuous carbon fibre composite materials produced by a modified 3D printer 
      Article dans une revue avec comité de lecture
      ccLE DUIGOU, Antoine; GRABOW, M.; CASTRO, M.; TOUMI, R.; UEDA, M.; MATSUZAKI, R.; HIRANO, Y.; ccDIRRENBERGER, Justin; SCARPA, F.; D'ELIA, R.; LABSTIE, K.; LAFONT, U. (Elsevier BV, 2023-02)
      First of all, this article aimed to evidence the role of a modified printer developed for continuous carbon fibre reinforced PolyAmide (cCF/PA6-I) together with the use of a fully open slicing step on the printing quality ...
