This book was released on 1970 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Room-temperature tensile properties were determined for large 7075-T6 and 7075-T73 aluminum-alloy forgings. Forging sizes ranged from about 1.5 to 15 inches (short-transverse direction) for production forgings and up to 20 inches for step forgings. Heat-treated thickness was 0.75 to 1.000 inch for the T6 temper but ranged up to 10 inches for the T73 temper. Regression coefficients and standard d deviations are presented for three properties (TUS, TYS, and elongation) in each of three test directions. In addition, average values and two statistical minima are tabulated for each property and test direction at each of several discrete sizes, and a comparison is made with the corresponding requirements of Specification MIL-A-22771C(ASG).

Available in PDF, EPUB and Kindle. Book excerpt: Accounting for fatigue loadings has been a concern ever since the widespread introduction of metallic materials into load-bearing components in the nineteenth century. Calculations were developed based on the analysis capabilities of their time incorporating all the latest technologies of their era. At the time, that technology was pencil-and-paper calculations. Today's calculations are computer-based. The widespread use of computing methods has greatly enhanced the analyst abilities for simulating internal stress and strain fields. Unfortunately, current fatigue analyses often force-fit current stress field calculations into fatigue analysis methods meant for nineteenth century stress calculation methods. It's never a good idea to force methods optimized for pre-computer calculations to work with computers. This text presents a more integrated approach to computer-based fatigue analysis methods. Like what was originally done, the latest technologies are applied rather than force-fitting computer computational capabilities into nineteenth-century techniques. Holistic approaches incorporating all knowledge have long been established as the most successful approach to problem-solving. Incorporating all knowledge with the most modern capabilities is the preferred approach. Holistic methods strive to reduce subjective inputs and replace them with consistent objective ones. This text aims to transition disjointed inefficient analyses into a unified computer-based holistic technique by introducing a fatigue analysis method specifically developed for computer simulations. Ultimately, for any method or theory to be valuable, it must be put into practice and prove itself. That entails leadership decision-making. Engineering design development activities will lead to final decisions. Information in a holistic approach must include the reliability of the information. How consistent are the predictions? Are the two types of potential scatter, analytic, and physical properly addressed? Is analytic scatter minimized while maintaining creativity? Is physical scatter totally understood? Effective program management requires knowledge on both types of scatter and, most importantly, the ability to realize the difference. A novel computer-based unified approach to fatigue methods is presented which incorporates a holistic approach for more accurate and consistent analyses, including the management and leadership of fatigue analysis projects, minimization of analytic scatter, management of physical scatter, and unification of methods that minimize subjective inputs often needed to bridge inconsistent techniques.

Available in PDF, EPUB and Kindle. Book excerpt: The first phase of an evaluation to determine the size effect on the fatigue properties of 7075-T651, 7079-T651 aluminum alloy stretcher leveled plates and an X7080 aluminum alloy hand forging has been completed. Evaluation of the large section specimens (4 square inches test section) showed that the fatigue strength of the X7080 aluminum alloy hand forging, 40,000 p.s.i. at 1, 000,000 cycles, was approximately 48% and 60% higher than the fatigue strengths of 27,000 p.s.i. and 25,000 p.s.i. for the 7075 and 7079 alloy stretcher leveled plates, respectively. The notched fatigue strength of the X7080 alloy, 14,000 p. s.i. at 1,000,000 cycles, was approximately 17% higher than the notched fatigue strength of 12,000 p.s.i. for the 7075 and 7079 alloys.
