    • Absorptivity measurement of solid and powder bed under IR laser beam 
      Article dans une revue avec comité de lecture
      KROMER, Robin; GORNY, Cyril; ccGRUHIER, Elise; LE GUEN, Emilie; ccARVIEU, Corinne; ccLACOSTE, Eric (Elsevier BV, 2023-01)
      The effective absorptivity of IR laser light for different powder beds were studied. The reflectivity of aluminum, titanium, stainless steel and copper alloys was measured using an appropriate Ulbricht sphere. Laser ...
    • Ultrasonic imaging of buried defects in rails 
      Article dans une revue avec comité de lecture
      ccRODRIGUEZ, Samuel; GAYOUX, Victor; ccDUCASSE, Eric; CASTAINGS, Michel; PATTEEUW, Nicolas (Elsevier BV, 2023-01)
      The present work addresses the ultrasonic NDT of rails, more precisely of the rail foot. The practical constraint is that transducers must be located on the rail head, whereas the region of interest is the rail foot. Thus, ...
    • Kinematic fields measurement during Ti-6Al-4V chip formation using new high-speed imaging system 
      Article dans une revue avec comité de lecture
      ZOUABI, Haythem; ccCALAMAZ, Madalina; WAGNER, Vincent; CAHUC, Olivier; DESSEIN, Gilles (Springer Science and Business Media LLC, 2023-01)
      Orthogonal cutting on Ti-6Al-4V produces segmented chips which results from localized deformation within the Primary Shear Zone (PSZ). For in situ visualization of the material flow during Ti-6Al-4V chip formation, a new ...
    • Uncertainty reduction in residual stress measurements by an optimised inverse solution using nonconsecutive polynomials 
      Article dans une revue avec comité de lecture
      BRÍTEZ, Diego L.; PRIME, Michael B.; ccWERDA, Sana; ccLAHEURTE, Raynald; DARNIS, Philippe; CAHUC, Olivier (Wiley, 2022-11-08)
      Many destructive methods for measuring residual stresses such as the slittingmethod require an inverse analysis to solve the problem. The accuracy of theresult as well as an uncertainty component (the model uncertainty) ...
    • The Role of Inertia in the Onset of Turbulence in a Vortex Filament 
      Article dans une revue avec comité de lecture
      ccCALTAGIRONE, Jean-Paul (MDPI AG, 2023-01-02)
      The decay of the kinetic energy of a turbulent flow with time is not necessarily monotonic. This is revealed by simulations performed in the framework of discrete mechanics, where the kinetic energy can be transformed into ...
    • Shifted boundary polynomial corrections for compressible flows: high order on curved domains using linear meshes 
      Article dans une revue avec comité de lecture
      ccCIALLELLA, Mirco; GABURRO, Elena; LORINI, Marco; RICCHIUTO, Mario (Elsevier BV, 2023-03)
      In this work we propose a simple but effective high order polynomial correction allowing to enhance the consistencyof all kind of boundary conditions for the Euler equations (Dirichlet, characteristic far-field and slip-wall), ...
    • Improvement of the self‐assembly of low χ ABA triblock copolymers with the addition of an ionic liquid 
      Article dans une revue avec comité de lecture
      ccGULIYEVA, Aynur; PUNG, Hélène; TENCE-GIRAULT, Sylvie; ccRÉBILLAT, Marc; ccSERGHEI, Anatoli; ccGERVAIS, Matthieu; ccSOLLOGOUB, Cyrille; ccROLAND, Sébastien (Online Library Wiley, 2022-11)
      Self-assembly of high molecular weight commercially available low χ ABA triblock copolymers with ionic liquids (ILs) was observed after solvent casting without the implementation of an additional annealing step. Here, the ...
