    • Coalescence modeling and experimental validation of sintering of thermoplastic polyamide fibers 
      Article dans une revue avec comité de lecture
      XU, Fan; LI, Xin; DEFAUCHY, Denis; ccREGNIER, Gilles (2013)
      In order to study the coalescence mechanisms of thermoplastic polymer powders, a 2D mathematical model has been established based on Frenkel, Eshelby and Pokluda’s model. Sintering experiments have been carried out by using ...
    • Influence of projectile shape on dynamic behavior of steel sheet subjected to impact and perforation 
      Article dans une revue avec comité de lecture
      KPENYIGBA, K. M.; JANKOWIAK, Tomasz; RUSINEK, Alexis; ccPESCI, Raphaël (Elsevier, 2013)
      The paper describes a work focused on the process of perforation of steel sheet.Experimental,analytical and numerical investigations have been carried out to analyze in details the perforation process.Based on these ...
    • Development and mechanical characterization of porous titanium bone substitutes 
      Article dans une revue avec comité de lecture
      BARBAS, Alexandre; BONNET, Anne-Sophie; LIPINSKI, Paul; DUBOIS, Guillaume; ccPESCI, Raphaël (Elsevier, 2012)
      Commercially Pure Porous Titanium (CPPTi) can be used for surgical implants to avoid the stress shielding effect due to the mismatch between the mechanical properties of titanium and bone. Most researchers in this area ...
    • Strain localization analysis using a multiscale model 
      Article dans une revue avec comité de lecture
      FRANZ, Gérald; ccABED-MERAIM, Farid; BEN ZINEB, Tarak; LEMOINE, Xavier; BERVEILLER, Marcel (Elsevier, 2009)
      In order to analyze the formability of steels in sheet metal forming, a ductility loss criterion is coupled with a multiscale model. The behavior at the mesoscopic (grain) scale is modeled by a large strain micromechanical ...
    • Method of determining the process applied for feature machining : experimental validation of a slot 
      Article dans une revue avec comité de lecture
      MARTIN, Patrick; ccALAIN, D'acunto (Springer Verlag, 2007)
      In this paper, we will be evaluating the "manufacturability" levels for several machining processes of "slot" feature. Using the STEP standard, we will identify the slot feature characteristics. Then, using the ascendant ...
    • Springback of thick sheet AHSS subject to bending under tension 
      Article dans une revue avec comité de lecture
      RACZ, Sever-Gabriel; ccCHALAL, Hocine; ccBALAN, Tudor (Elsevier, 2012)
      The springback behavior of four advanced high-strength sheet steels (Dual-Phase, TRIP, ferrite-bainite) with thicknesses ranging from 1.2 to 4 mm was investigated by means of the bending-under-tension (BUT) test. The ...
    • Experimentally valided approach for the simulation of the forging process using mechanical vibration 
      Article dans une revue avec comité de lecture
      LY, Rith; ABBA, Gabriel; ccGIRAUD-AUDINE, Christophe (Springer Verlag, 2009)
      In this study, an experimental setup of a forging process has been designed which allows to apply vibrations to the lower die of amplitude ranging from 0 to 80 ?m at frequencies varying from 1 to 130Hz thanks to the use ...
