Crack Propagation Test Results for Variable Amplitude Spectrum Loading in Surface Flawed D6ac Steel.

Abstract

This report contains the results of spectrum crack growth tests of surface flawed D6ac plate materials. All spectra used in the program represented the critical wing pivot locations for the F-lll aircraft and were applied in a randomized block sequence containing 58 layers representing 200 flight hours. The effects of limited compression and the single overload proof test cycle were evaluated.
