Trends in increasing usage of aluminum-alloys for vehicle safety components require to summarize the state of the art related to the approval of their service strength including the aspects of reliability and safety. For this, it is necessary to describe the design criteria for the vehicle safety components manufactured from aluminum-alloys, which include the evaluation of the structural yield point, the fracture behaviour and the fatigue life - three main parameters for the components service strength. In this project the procedures for the experimental and the numerical service strength evaluation of cast, forged and welded aluminum-alloy safety components are presented. Also the results of investigations about environmental influences (corrosion, elevated temperature) as well as the methods for accelerated test approval are presented, validated and a practical approach recommended. Finally, further investigations are proposed being of importance to determine additional data necessary for a reliable design.
