Strain behaviour of friction stir welding of dissimilar materials
Friction stir welding (FSW) is generally used to join aluminium alloys. The present literature available for FSW is mainly based on the experiments at constant amplitude loading (CAL), and there are questions on the verification of the benefits of FSW at variable amplitude loading (VAL), the latter being more realistic of service loadings. In VAL, tensile overloads may interact with other mechanisms such as yielding or fracture while compressive overloads may have significant influence on local buckling, relaxing the stress field or producing secondary bending, and thus shorten the fatigue life. Questions such as: why, how and under what conditions this effect occurs or what damage mechanisms play a dominant role, remain unanswered. The objective of this project aims to solve the damage mechanisms of dissimilar aluminium joints manufactured with FSW by considering fatigue tests at service loading, investigating the microstructures and developing analytical approaches. The scientific approach includes investigations on the development of grain structure size and orientation through the depth of the weld by neutron scattering, and on the relation of stress state at service loading
