Présentation
Sandrine Thuillier est professeur des universités en mécanique depuis 2009 à l'Université Bretagne Sud (France). Ses activités de recherche portent sur la caractérisation expérimentale du comportement mécanique des matériaux à température ambiante et élevée, principalement des tôles d'alliages d'aluminium, d'aciers et d'alliages de titane, et dans une moindre mesure, des élastomères et des composites thermoplastiques. Elle concentre également ses efforts sur l'identification des paramètres des matériaux par méthode inverse, car ces paramètres sont une donnée d'entrée essentielle pour les modèles numériques fondés sur l'élasto-visco-plasticité, la limite d'élasticité anisotrope, l'endommagement ductile et la rupture macroscopique. Enfin, elle applique ses compétences scientifiques aux processus de mise en forme des métaux, tels que l'emboutissage, les défauts de surface, la flexion, la torsion et l'assemblage par déformation plastique, comme le sertissage et le clinchage. Depuis 2022, elle est directrice de l'école doctorale SPI.bzh n°647 Depuis décembre 2023, elle est présidente de la section CNU60 (Conseil National des Universités),
