Activités de recherche :

Ma thématique de recherche concerne le comportement mécanique des matériaux métalliques et notamment l'étude des effets thermiques associées aux sollicitations mécaniques. Mes activités se décomposent principalement en trois axes

  • Etude du comportement des matériaux métalliques sous sollicitation dynamique et études des effets thermiques associés : application aux procédés de mise en forme dynamiques : poinçonnage dynamique, usinage grande vitesse, cisaillement adiabatique.
  • Etude des mécanismes de déformation et de rupture dans les métaux : application à l'effet Portevin Le Chatelier, fatigue à grand et très grand nombre de cycle
