| Summary: | Results of tensile and bend tests on specimens in the T6 condition from 12- to 24-inch hand forgings of 7075 (75S) and 2014 (14S) aluminum alloy are presented in this report. Thirty-six notched bend specimens were tested as cantilever beams together with 48 tensile specimens of material adjacent to the bend specimens. Two-thirds of the bend specimens were 1/4 inch wide. In these, the critical extreme fiber stresses were unidirectional. The rest of the bend specimens were 6 inches wide. In these, there were biaxial stress conditions at the critical extreme fiber. The specimens were taken in the axial direction and in both transverse directions. Photogrids were applied to all specimens. The photogrids were photographed at frequent intervals during each test to provide a record of the progres of deformation |
