Description
Similar and dissimilar T-joints were made by friction stir welding (FSW) of 3 mm thickness 2024-T3 cover sheet combined with 2.5 mm thick stiffeners consisting of either 2024-T3 or 2098-T8 (stringer) material. During welding the pin penetrated the stringer to ensure effective mixing of both components. The T joints were analysed by microstructural inspection, hardness profiles and tensile behaviour. Emphasis was placed on the cyclic and monotonic crack growth perpendicular to the joint line in single-edged notched tension (SENT) specimens and 2-stringer panels. The evaluation of cut-compliance measurements developed for flat coupon specimens was transferred to T-joints in order to determine residual stresses.
