    • Micromechanics-Based Damage Analysis of Fracture in Ti5553 Alloy with Application to Bolted Sectors 
      Article dans une revue avec comité de lecture
      ccBEN BETTAIEB, Mohamed; VAN HOOF, Thibaut; MINNEBO, Hans; PARDOEN, Thomas; DUFOUR, Philippe; JACQUES, Pascal J.; HABRAKEN, Anne-Marie (Springer Verlag/ASM International, 2015)
      A physics-based, uncoupled damage model is calibrated using cylindrical notched round tensile specimens made of Ti5553 and Ti-6Al-4V alloys. The fracture strain of Ti5553 is lower than for Ti-6Al-4V in the full range of ...
    • Non-quadratic anisotropic potentials based on linear transformation of plastic strain rate 
      Article dans une revue avec comité de lecture
      KIM, Daeyong; BARLAT, Frédéric; BOUVIER, Salima; RABAHALLAH, Meziane; CHUNG, Kwansoo; ccBALAN, Tudor (Elsevier, 2007)
      In this paper, anisotropic strain rate potentials based on linear transformations of the plastic strain rate tensor were reviewed in general terms. This type of constitutive models is suitable for application in forming ...
    • Influence of material structure on deep hole machinability of Super High Strength Steels 
      Article dans une revue avec comité de lecture
      BOMONT-ARZUR, Anne; CONFENTE, Mario; BOMONT, Olivier; SCHNEIDER, Emmanuel; BOMONT-ARZUR, Anne; ccLESCALIER, Christophe (Inderscience, 2007)
      The gain of productivity in machining is generally sought through tools and/or cutting conditions optimization however an increase in productivity is achievable too through the workmaterial optimization. The metallurgical ...
    • A comparative study of Forming Limit Diagrams predicted by two different plasticity theories involving vertex effects 
      Article dans une revue avec comité de lecture
      AKPAMA, Holanyo K.; ccBEN BETTAIEB, Mohamed; ccABED-MERAIM, Farid  (Trans Tech Publications, 2015)
      The main objective of this contribution is to compare the Forming Limit Diagrams (FLDs) predicted by the use of two different vertex theories. The first theory is micromechanical and is based on the use of the ...
    • Stress and heat flux distribution in rake face. Analytical and experimental approaches 
      Communication avec acte
      ARTOZOUL, Julien; BOMONT-ARZUR, Anne; ccLESCALIER, Christophe; D’ACUNTO, Alain (ENIM Editions, 2010)
      Metallurgical solutions for an improvement in machinability currently use nonmetallic inclusions in order to create solid lubricants at the interfaces between tool and workmaterial. It is possible to identify and quantify ...
    • Extended infrared thermography applied to orthogonal cutting 
      Article dans une revue avec comité de lecture
      ARTOZOUL, Julien; BOMONT, Olivier; DUDZINSKI, Daniel; ccLESCALIER, Christophe (Elsevier, 2014)
      The temperature knowledge is essential to understand and model the phenomena involved in metal cutting. A global measured value can only provide a clue of the heat generation during the process; however the deep understanding ...
    • Plastic Instability Based on Bifurcation Analysis: Effect of Hardening and Gurson Damage Parameters on Strain Localization 
      Article dans une revue avec comité de lecture
      MANSOURI, Lotfi; ccCHALAL, Hocine; ccABED-MERAIM, Farid ; ccBALAN, Tudor (Trans Tech Publications, 2012)
      In this work, we propose to couple the Gurson-Tvergaard-Needleman (GTN) model, known for its widespread use to describe damage evolution in metallic materials, to the Rice localization criterion. ...
