摘要

Constant amplitude loading fatigue crack growth rate test data were generated for aluminum alloy 2024-T351 at 20 test conditions: the combination of five load ratios, 0.01, 0.1, 0.3, 0.5, and 0.6 and four test temperatures, 72 degrees, 200 degrees, 300 degrees, and 400 degress F (22 degrees, 93 degrees, 149 degrees, and 204 degrees C, respectively). A mathematical model of the shift in the linear data region with the variation in test temperature and/or load ratio was formulated. The model approximates the log-Paris coefficient as a linear relationship of both the R-ratio and test temperature assuming all other test parameters remain constant. (Author)
