Etude expérimentale et modélisation du comportement mécanique du combustible UO2 en compression à haute température et forte vitesse de sollicitation

Etude expérimentale et modélisation du comportement mécanique du combustible UO2 en compression à haute température et forte vitesse de sollicitation

L'objectif de ce travail est de caractériser et de modéliser le comportement mécanique des oxydes d'uranium (UO2) en situation d'Accident d'Injection de Réactivité (RIA). Les sollicitations vues par le combustible durant un RIA sont caractérisées par de fortes vitesses de déforma...
