Innovative fatigue and damage tolerance methods for the application of new structural concepts

Obiettivo

In order to allow the industry to use newly developed manufacturing methods, which all promise high efficiency but lack a good damage tolerance capability under certain circumstances, the proposed project aims to develop new damage tolerance assessment tools for the new and high performance manufacturing techniques: High Speed Cutting (HSC), Laser Beam Welding (LBW) and Friction Stir Welding (FSW), all three leading to a type of structure which is close to an ntergral structural design. This design offers benefits, e.g. from the cost point of view, but also some concerns from the damage tolerance capacity point of view. Since the damage tolerance behavior of structures s a crucial point in the application of the new techniques, it limits today it's application. Therefore, the DaToN project provides an important step forward for strengthening competitiveness of the European aeronautic industry by contributing to the aircraft development and operating costs reduction via the development of advanced and high damage tolerance performance structural concepts using bothnew automated fast manufacturing processes and new metallic materials for optimizing the inducedstructural weight reduction.The present proposal aims to provide missing fundamental knowledge and assessment tools for the damage tolerance of integrally stiffened structures, which are produced by means of the three new production methods: LBW, FSW and HSC.The project does not aim to develop the manufacturing techniques. The main scientific and technological objectives of the project are : o To develop and validate calculation tools for the assessment and the understanding of the damage tolerance behaviour of integrally stiffened structures using high performance manufacturing processes : High Speed Cutting. Laser beam Welding and Friction Stir Welding. o To analyze the impact of the manufacturing process on the fatigue and damage tolerance behaviour
