1965) the transverse direction (Schijve and de Rijck 1966). However, CA tests revealed no consistent differences in fatigue life for both cases of the riveted specimen orientation, Fig. 1 (Hartman et al. 1965). In general, 2024-T3 Alclad is slightly superior to the 7075-T6 clad alloy with respect to their fatigue properties, but its static strength is lower. If a high static tensile strength is required for a component, the relatively high Sy and Su of 7075T6 can be advantageous compared to the lower values for 2024-T3.
Laboratory tests on small specimens can be useful in research on corrosion damage only if during manufacturing and assembling of the test pieces the production standards are maintained. However, laboratory tests cannot fully account for environmental effects. Fatigue tests under uniaxial loading provide conservative results on the fatigue performance of flat, biaxially loaded riveted specimens. When uniaxially loaded specimens are tested, the so-called edge effect (difference in the lateral contraction in two overlapping sheets) occurs.
1 Stress Distribution and Specimen Geometry 15 Fig. 6 Stress distribution for lap joints in wide panels with tear straps: (a) panel geometries; (b) FE results (Furuta et al. 1997) The Type-3 panel had a constant width tear strap. The tear strap width in the Type-4 panel was narrowed compared to the Type-3 specimen except at the spliced area. FE analysis results shown in Fig. 6b indicate that the narrowing of the tear strap width causes a substantial increase in the stress in the skin splice. 5.
