title = "Specimen thickness effects on front edge shape of fatigue crack in Al7075-T6 alloy",
abstract = "In this study, crack front edge shape due to the difference in the specimen thickness was investigated using aluminum alloy 7075-T6. The curvature radius of the fatigue crack front edge decreased as the specimen thickness decreased. According to the study by Camas et al., the plastic zone size at the specimen surface is larger than that at the center of the specimen thickness. As the curvature radius of the crack front edge becomes smaller, the difference between the plastic zone size at the specimen surface and that at the center of the specimen thickness becomes large. As a result, the specimen surface effect appears more strongly in thin specimen. This Camas{\textquoteright}s result is in agreement with the characteristics obtained in this study that PIFCC appears remarkably when the specimen is thin.",
