Detailed knowledge of microstructure and related fatigue crack growth behaviour of the investigated sheet alloys

- Detailed knowledge on microstructure and related fatigue and crack growth behaviour of the investigated sheet alloys

- Models will be derived, describing the mechanical properties and fatigue behaviour of the investigated alloys, i. e. the effect of their microstructure on these properties. These models will assist in a more precise definition of exact requirements for new aluminium sheet alloys.

- Identification of microstructural parameters governing fatigue and crack growth characteristics of aluminium sheet alloys, increasing the knowledge on the mechanisms producing fatigue damage in materials. This better understanding of the fatigue and crack growth processes could lead to a revision of design data, and may result in significant improvements in the efficiency of aeronautical structures.
