Book Description
Tests were made of a number of 10-inch shear panels of 24S-T aluminum alloy with 1- 1/2-inch holes to determine the stress concentrations at static rupture and the deformation characteristics. The average factor of stress concentration was found to be about 1.1; reinforcements around the edges of the holes did not increase the ultimate strengths. Permanent set began in specimens without holes at nominal shear stresses of 10 to 12 kips per square inch. In thin specimens with holes, permanent set began at the buckling stress.
