    • Size and build strategy effects for the L-PBF process applied to Inconel 625 vertical struts: a combined numerical and experimental approach 
      Article dans une revue avec comité de lecture
      ccPEYRE, Patrice; RODRIGUES DA SILVA, Julien; HAMOUCHE, Zehoua; HELBERT, Anne-Laure; ccDALIGAULT, Julien; ccDAL, Morgan; COSTE, Frédéric; BAUDIN, Thierry (Springer Nature (Research Square Platform LLC), 2024-01-22)
      A combined numerical and experimental analysis of melt-pool dimensions and resulting solidification conditions was carried out on small laser powder bed fusion (L-PBF) struts (0.2 mm to 2 mm diameters), considered as single ...
    • Influence of laser wavelength on the powder bed fusion of pure copper 
      Article dans une revue avec comité de lecture
      ccNORDET, Guillaume; GORNY, Cyril; COSTE, Frédéric; ccLAPOUGE, Pierre; EFFERNELLI, Albin; BLANCHET, Etienne; ccPEYRE, Patrice (Springer Science and Business Media LLC, 2024-07)
      In the current work, and for the first time, two 1 kW continuous wave (CW) lasers, with green and infrared (IR) wavelengths, were used to manufacture pure copper with the laser powder bed fusion (LPBF) process. Copper is ...
    • Damage identification technique by model enrichment for structural elastodynamic problems 
      Article dans une revue avec comité de lecture
      ccDI LORENZO, Daniele; RODRIGUEZ, Sebastian; ccCHAMPANEY, Laurent; ccGERMOSO, Claudia; ccBERINGHIER, Marianne; ccCHINESTA SORIA, Francisco (Elsevier BV, 2024-06)
      Structural Health Monitoring (SHM) techniques are key to monitor the health state of engineering structures, where damage type, location and severity are to be estimated by applying sophisticated techniques to signals ...
    • Instability and rupture of sheared viscous liquid nanofilms 
      Article dans une revue avec comité de lecture
      DHALIWAL, Vira; PEDERSEN, Christian; KADRI, Kheireddin; ccMIQUELARD-GARNIER, Guillaume; ccSOLLOGOUB, Cyrille; ccPEIXINHO, Jorge; ccSALEZ, Thomas; CARLSON, Andreas (American Physical Society (APS), 2024-02)
      Liquid nanofilms are ubiquitous in nature and technology, and their equilibrium and out-of-equilibrium dynamics are key to a multitude of phenomena and processes. We numerically study the evolution and rupture of viscous ...
    • Spatio-temporal physics-informed neural networks to solve boundary value problems for classical and gradient-enhanced continua 
      Article dans une revue avec comité de lecture
      ccNGUYEN, Duc-Vinh; ccJEBAHI, Mohamed; ccCHINESTA SORIA, Francisco (Elsevier BV, 2024-08)
      Recent advances have prominently highlighted physics informed neural networks (PINNs) as an efficient methodology for solving partial differential equations (PDEs). The present paper proposes a proof of concept exploring ...
    • Predicting the post-bifurcated patterns of architectured materials using group-theoretic tools 
      Article dans une revue avec comité de lecture
      ccAZULAY, Rachel; ccCOMBESCURE, Christelle (Elsevier BV, 2024-03)
      Extensive studies on hexagonal honeycombs under in-plane compression have demonstrated that the structure's symmetry plays a decisive part in the emergence of deformation patterns in post-bifurcated configurations. In this ...
    • First-principles study of grain-boundary wetting in Fe-Σ5(013)[100] tilt boundary 
      Article dans une revue avec comité de lecture
      ccAUGER , Thierry; ccWANG, Linlin; JOHNSON, Duane D.; GONG, Xing (Elsevier BV, 2023-12)
      We report an ab-initio study of grain-boundary wetting (GBW) in three systems (Fe/Zn, Fe/Pb & Fe/Bi) on a Σ5(013)[100] tilt grain boundary. An energy-based approach is pursued and adapted to the study of liquid-metal/solid-metal ...
