NACA Technical Notes

Note presenting a description of equipment and test technique used in the creep testing of lap joints. Riveted aluminum-alloy joints fabricated from 75S-T6 and 24S-T3 sheet with 24S and 24S-T31 rivets were tested at 300, 400, and 500 degrees Fahrenheit. The test results showed that the creep of the riveted joints is considerably greater than the creep of the unriveted sheet although not so large that the creep of the sheet is negligible compared with that of the joints

NACA Technical Notes

"The results of 55 creep and creep-rupture tests on structural joints are presented. Methods are described by which the time to rupture, the mode of rupture, and the deformation of joints in creep may be predicted. These methods utilize creep data on the materials of the joint in tension, bearing, and shear" (p. 1)

NACA Technical Notes

Note presenting tests performed on 21 sheet-stringer panels of 75S-T6 aluminum alloy with alclad sheets nominally 0.051 inch thick and stringers nominally 3.5 inches apart. Three panels of different types, with five stringers each and overall dimensions of approximate 18 by 15 inches, were tested in axial flat-end compression. Results regarding the flat-end compression, protruding-stringer compression, and bending are provided

NACA Technical Notes

Note presenting testing under combined axial load and lateral pressure on 12 bonded sandwich panels with simply supported loaded edges and free unloaded edges. The maximum load and mode of failure were observed for all the panels. Lateral deflections and axial strains were also measured
