Some Strength Tests of Stiffened Curved Sheets Loaded in Shear

Report discusses the results of strength tests of several curved-sheet 24S-T aluminum alloy specimens stiffened longitudinally and transversely and loaded in shear. Curved-web beams and cylindrical shells were both examined in the tests. Results provided include the load at which the sheet began to show shear buckles, where the buckles occurred, and whether or not the failures involved rupture of the sheet.

Tests of 10 Inch 24S-T Aluminum-Alloy Shear Panels With 1-1/2 Inch Holes 2: Panels Having Holes With Notched Edges (open access)

Tests of 10 Inch 24S-T Aluminum-Alloy Shear Panels With 1-1/2 Inch Holes 2: Panels Having Holes With Notched Edges

Report discusses the results of testing of 10-inch 24S-T aluminum alloy shear panels with 1.5 inch holes with notched edges to determine if a notch decreases the strength of the panel and if reinforcements can overcome the negative effects of the notch. The notch did appear to increase the stress concentration around the holes, but the lack of applicability to real-world scenarios is discussed.
