Download or read book Investigation of Statistical Nature of Fatigue Properties written by E. Epremian and published by . This book was released on 1952 with total page 746 pages. Available in PDF, EPUB and Kindle. Book excerpt: Extensive fatigue tests were made on annealed Armco iron and plain carbon and alloy steels heat-treated to different strengths and microstructures. Statistics of fatigue-fracture curves and endurance limits were determined from the experimental data obtained and, for various other materials, from a survey of literature. The results were analyzed to show the relative effects of various metallurgical factors on the statistical nature of fatigue properties. Other phases of the problem studied include: dependence of statistical variation in fatigue life on stress level in the fracture range, statistics for location of crack initiation, size effect, understressing effect, and the form and method of plotting the S-N diagram.

Book excerpt: Autoradiography has been used only to a rather limited extent in metallurgical studies. Probably the major deterring factor has been that the autoradiographic systems have not provided the high resolution required in many investigations. A general discussion of the requirements for high-resolution autoradiography is presented in this report including detecting layer as well as radioactive-sample specifications. The need for a thin photographic emulsion in close contact with the metal surface is emphasized. The desirability of using favorable radiation (e.g., low-energy beta radioactivity) is also discussed.

Download or read book An Experimental Investigation of Secondary Flow in an Accelerating Rectangular Elbow with 90 Degrees of Turning written by John D. Stanitz and published by . This book was released on 1953 with total page 684 pages. Available in PDF, EPUB and Kindle. Book excerpt: The passage vortex associated with secondary flows appears to be near the suction surface and away from the plane wall of the elbow at the exit and does not have appreciable spanwise motion as it moves downstream the elbow exit. As the spoiler size increases, the boundary-layer form changes and a rather sudden difference in the secondary flow occurs, perhaps associated withthe reduced importance of viscous effects in thick boundary layers. It is suggested that the strength of the secondary vortices is small and that the energy of secondary flows is small.

Download or read book Developments in Lightweight Aluminum Alloys for Automotive Applications written by James M Boileau and published by SAE International. This book was released on 2006-02-03 with total page 551 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of lightweight materials in automotive application has greatly increased in the past two decades. A need to meet customer demands for vehicle safety, performance and fuel efficiency has accelerated the development, evaluation and employment of new lightweight materials and processes. The 50 SAE Technical papers contained in this publication document the processes, guidelines, and physical and mechanical properties that can be applied to the selection and design of lightweight components for automotive applications. The book starts off with an introduction section containing two 1920 papers that examine the use of aluminum in automobiles.
