    • Optimization of gaseous nitriding of steels by multi-physics modelling 
      Communication avec acte
      FALLOT, Guillaume; BARRALLIER, Laurent; ccJÉGOU, Sébastien (ASM International, 2016)
      Gaseous nitriding is controlled by temperature, time and surface nitrogen potential. Tuning these parameters lead to the expected mechanical properties (hardness, residual stresses) and durability of treated mechanical ...
    • Scaling invariance of fatigue crack growth in gigacycle loading regime 
      Article dans une revue avec comité de lecture
      OBORIN, V.; BANNIKOV, M.V.; NAIMARK, O.B; ccPALIN-LUC, Thierry (MAIK Nauka/Interperiodica (МАИК Наука/Интерпериодика), 2010)
      The role of the collective behavior of defect ensembles at the crack tip and the laws of fatigue crack propagation in R4 high-strength steel have been studied under conditions of symmetric tension-compression gigacycle ...
    • Implicit implementation and consistent tangent modulus of a viscoplastic model for polymers 
      Article dans une revue avec comité de lecture
      ACHOUR, Nadia; CHATZIGEORGIOU, George; ccMERAGHNI, Fodil; CHEMISKY, Yves; ccFITOUSSI, Joseph (Elsevier, 2015)
      In this work, the phenomenological viscoplastic DSGZ model (Duan et al., 2001 [13]), developed for glassy or semi-crystalline polymers, is numerically implemented in a three-dimensional framework, following an implicit ...
    • Traitement de nitruration et durabilité des pièces mécaniques 
      Communication avec acte
      BARRALLIER, Laurent; ccJÉGOU, Sébastien (2015)
      Le traitement thermochimique de nitruration est un traitement de surface permettant d'améliorer la durée de vie en fatigue des pièces traitées. Les dernières avancées dans ce domaine permettent de définir les paramètres ...
    • FRICTION AND WEAR BEHAVIOUR OF Ti-6AI-7Nb BIOMATERIAL ALLOY 
      Communication avec acte
      LABAIZ, Mohamed; FELLAH, Mamoun; ASSALA, Omar; IOST, Alain (Société Tribologique de France, 2013)
      Titanium and its alloys have been used as implant materials due to their very good mechanical and corrosion resistance and biocompatibility [1,2]. The most used biomaterials were commercially pure titanium (CP-Ti} issued ...
    • Determination of cavitation load spectra—Part 2: Dynamic finite element approach 
      Article dans une revue avec comité de lecture
      ROY, Samir Chandra; FRANC, Jean-Pierre; ccRANC, Nicolas; FIVEL, Marc (Elsevier, 2015)
      Cavitation erosion is a well-known problem in fluid machineries which occurs due to repeated hydrodynamic impacts caused by cavitation bubble collapse. Cavitation pitting test is often used for the quantification of flow ...
    • Synthesis of different types of energy based controller for a Modular Multilevel Converter integrated in a HVDC link 
      Communication avec acte
      SAMIMI, Shabab; DELARUE, Philippe; GUILLAUD, Xavier; ccGRUSON, Francois (IET, 2015)
      Modular Multilevel Converters are becoming increasingly popular with the development of HVDC connection and, in the future, Multi Terminal DC grid. A lot of publications have been published about this topology these last ...
