Objectif(s)
Macroscopic consequences of irradiation damage in terms of mechanical properties (hardening and embritlement), dimensional stability (growth and swelling) and environmental resistance.
Physical based models in relation with microstructural evolution under irradiation (irradiation creep), physically based models of material mechanical properties post irradiation (hardening, local approach to fracture)
