摘要: In this study, in order to investigate crack retardation behavior and the variability of cycles, growth tests are conducted on 7075-T6 aluminum alloy under a single tensile overload. A coefficient D is introduced herein as ratio rate constant amplitude loading after an This separately formulated according composed delayed part part. To describe growth, statistical equation was developed by modifying Forman adding random variable Z it previous study. By using definition law, cycles overload predicted. The prediction method presents representative agrees with experimental data. Especially, predicts distribution very well.
