An Investigation of Strain Concentration in High-Strength Al-Zn-Mg-Cu Alloy 7085 Subjected to Tensile Deformation

The strain concentration factors were determined for aluminum alloy 7085 in the T7651 temper using multi-hole structural coupon specimens. Samples of the alloy were evaluated for both the 6.25 mm (0.25 in.) thick and 10 mm (0.4 in.) thick specimens having widths of 50 mm (2 in.) and 100 mm (4 in.),...
