In this study, surface fatigue crack nucleation and microstructurally small crack growth in high strength aluminum alloys, commonly used in aerospace applications, are evaluated through a holistic approach encompassing fatigue testing, crack measurement, and computational prediction of crack growth rates. As such, specific and targeted experimental and computational methods are necessary to accurately capture and predict the discrete behavior of microstructurally small fatigue cracks. It is well established that fatigue crack nucleation and small crack growth in high strength aluminum alloys are highly influenced by the surrounding microstructure including grain boundaries, texture, inclusion barriers, among other factors. 4Boeing Research and Technology, The Boeing Company, Berkeley, MO, United States.3Department of Metallurgical and Materials Engineering, The University of Alabama, Tuscaloosa, AL, United States.2Department of Mechanical Engineering, The University of Alabama, Tuscaloosa, AL, United States.1Department of Mechanical, Aerospace, and Biomedical Engineering, The University of Tennessee, Knoxville, TN, United States.Thanks to the Supreme Court, it may.Robert Fleishel 1, Cole Cauthen 2, Steven Daniewicz 3, Andrew Baker 4, J. If Quebec is bent on subjecting its population to the cumbersome, intrusive, and largely pointless inconvenience of a long-gun registry, it should at least try to do it right. Building a new version using this data guarantees that Quebec would simply be recreating all the problems of its deeply troubled federal predecessor. The records have hardly become more accurate in the three years since the registry was shut down. The data it contained was made even more unreliable by a series of amnesties the federal Conservatives declared in the minority government era, making compliance effectively voluntary. The long-gun registry was riddled with inaccurate and out of date information from the start. That has always meant, not hauling the old federal registry data out of mothballs, but starting from scratch and collecting it all over again. If that’s the case, it should surely wish to create the most accurate registry possible. Quebec insists the long-gun registry is a matter of public safety (as opposed, say, to empty symbolism or political theatre, as it has always seemed to us).
