    - basic knowledge on metallurgy, crystal plasticity, dislocation theory
    - basic knowledge on ceramic
    - basic knowledge on photon/mater interaction (Xray radiography, Xray diffraction)

Compétences attestées (transversales, spécifiques) :

knowledge, understanding, skills, abilities
    - understanding the physical origin of fracture for the different classes of materials.
    - distinguishing ductile/Brittle behaviors
    - using materials selection methods based on material index for performance
