Résumé

Aluminum alloys are important materials for primary aircraft structures due to their specific mechanical properties, established design and manufacturing methods, good fatigue and corrosion resistance. Aluminum is relatively cheap when compared with other metallic and composite materials in terms of manufacturing and maintenance cost. The 2XXX and 7XXX aluminum alloys are two of the most common series used for airframes, the former series having copper as the main addition element while the latter series has zinc as the main addition element. Aeronautical structures may be subjected to overloading as encountered during impact loading, including e.g. hail storm or bird strike. It is thus of major interest to know the behavior of the constitutive materials under high strain rate loading. We are here studying the dynamic failure of 2024 and 7075 aluminium alloys.
