Fracture angles and plastic strain ratios (r values) for aluminum alloys 2036-T4, 3004-H19, 5182-O, and 5352-H19 were determined and compared to the theoretical relationship between localized necking angle and r value. Data determined for 3004-H19 and 5352-H19 specimens, which exhibit minimal diffuse necking prior to localized necking, follow the theoretical relationship, while data determined for 2036-T4 and 5182-O specimens, which exhibit considerable diffuse necking, do not. Empirically determined fracture angle correction terms were developed for 2036-T4 and 5182-O to permit reasonable estimates of r based on the theoretical relationship.
