✦ Synopsis
Correlations are shown between the plane strain fracture toughness, K,,, and the notch tensile/yield strength ratios, NTS/YS, for 2124-T85l alloy. Over 100 data points were available in each of the three conventional testing directions. Results indicate that the sharp notch tension test could have reduced by 50% the more expensive K,= testing with a high degree of confidence based on proposed minimum K,, values. Little difference was shown in examining the toughness in various locations within a large 2219-T85l plate. However, specimen size effects are shown in these alloys.
