    • On the nucleation of deformation twins at the early stages of plasticity 
      Article dans une revue avec comité de lecture
      ABDOLVAND, Hamidreza; LOUCA, Karim; ccMAREAU, Charles; MAJKUT, Marta; WRIGHT, Jonathan (Elsevier BV, 2020-07-20)
      Understanding the deformation mechanisms of hexagonal close-packed (HCP) polycrystals at the grain scale is crucial for developing both macro and micro scale predictive models. Slip and twinning are the two main deformation ...
    • Formation and annihilation of stressed deformation twins in magnesium 
      Article dans une revue avec comité de lecture
      LOUCA, Karim; ABDOLVAND, Hamidreza; ccMAREAU, Charles; MAJKUT, Marta; WRIGHT, Jonathan (Springer Science and Business Media LLC, 2021-01-13)
      The mechanical response of polycrystalline materials to an externally applied load and their in-service performance depend on the local load partitioning among the constituent crystals. In hexagonal close-packed polycrystals ...
    • Heat treatment simulation of Ti-6Al-4V parts produced by selective laser melting 
      Article dans une revue avec comité de lecture
      CARDON, Amandine; ccMAREAU, Charles; ccAYED, Yessine; VAN DER VEEN, Sjoerd; GIRAUD, Eliane; DAL SANTO, Philippe (Elsevier BV, 2020-12-17)
      The present work focuses on the simulation of the heat treatment applied after printing of Ti-6Al-4V parts. The numerical tool aims at predicting the influence of heat treatment conditions (e.g. holding time, temperature) ...
    • Why does the quality of sketches in virtual reality depend so much on individuals? Analysis and identification of factors based on laboratory and field experiments 
      Communication avec acte
      CHANIAUD, Noémie; ccFLEURY, Sylvain; POUSSARD, Benjamin; ccCHRISTMANN, Olivier; GUITTER, Thibaut; ccRICHIR, Simon (2022)
      Virtual reality (VR) sketching tends to be democratized in the early stages of design for several reasons (e.g., improved creativity). Nevertheless, our field studies and the scientific literature identified some constraints ...
    • Influence of surface integrity on the fatigue behaviour of a hot-forged and shot-peened C70 steel component 
      Article dans une revue avec comité de lecture
      GERIN, Benjamin; ccPESSARD, Etienne; ccMOREL, Franck; VERDU, Catherine (Elsevier BV, 2017-01-14)
      Hot-forging is a process commonly used in the manufacturing of automobile parts such as connecting rods. Most hot-forged components are shot-blasted after forging in order to clean off the forging scale. The shotblasting ...
    • Fatigue behaviour of gear teeth made of case hardened steel: from competing mechanisms to lifetime variability 
      Communication avec acte
      ARGOUD, Vincent; ccMOREL, Franck; ccPESSARD, Etienne; ccBELLETT, Daniel; THIBAULT, Simon; GOURDIN, Stéphane (Elsevier BV, 2019-12-24)
      Jet engines gears are generally made of steel and are case-strengthened via thermochemical treatments such as carburizing or nitriding causing microstructural modifications, superficial hardening and compressive residual ...
    • Fatigue size effect due to defects in an AA7050 alloy 
      Communication avec acte
      ccABROUG, Foued; ccPESSARD, Etienne; ccGERMAIN, Guénaël; ccMOREL, Franck (EDP Sciences, 2018-05-25)
      One objective of this project is to propose a fatigue design approach that is able to account for a large range of machining surface defects and different component sizes and geometries. Due to the huge size difference ...
