Book Synopsis Investigation of Statistical Nature of Fatigue Properties by : E. Epremian
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 Synopsis Statistical Analysis of Fatigue Data by : R. E. Little
Download or read book Statistical Analysis of Fatigue Data written by R. E. Little and published by ASTM International. This book was released on 1981 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is commonly assumed in analysing fatigue data that there is a definite functional relationship between life in number of cycles and stress level. However, as has been pointed out several times (1, 2), an examination of the data shows considerable scatter. Even with carefully prepared smooth specimens, all from the same heat of steel, treated in the same manner and tested in the same laboratory, a range of 2 to 1 in number of cycles for failure at the same stress level is normal (1) and a range of 10 to 1 is not unusual (2). If the specimens are tested by different laboratories, slightly varying techniques will introduce further scatter (3).

Book Synopsis A Theory for Predicting the Flow of Real Gases in Shock Tubes with Experimental Verification by : Robert L. Trimpi
Download or read book A Theory for Predicting the Flow of Real Gases in Shock Tubes with Experimental Verification written by Robert L. Trimpi and published by . This book was released on 1955 with total page 674 pages. Available in PDF, EPUB and Kindle. Book excerpt: The nonlinear characteristic differential equations applicable to a quasi-one-dimensional unsteady channel flow with friction and heat transfer are linearized and integrated in functional form for the particular study of small perturbations from ideal shock-tube flows. If the equivalence of unsteady- and steady-flow boundary layers is assumed, the problem of determining the perturbation in the unsteady flow reduces to an evaluation of the drag of a flat plate in the equivalent steady flow.
Book Synopsis An Experimental Investigation of Secondary Flow in an Accelerating, Rectangular Elbow with 90 Degrees of Turning by : John D. Stanitz
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.
Book Synopsis Mechanical Vibration and Shock Analysis, Fatigue Damage by : Christian Lalanne
Download or read book Mechanical Vibration and Shock Analysis, Fatigue Damage written by Christian Lalanne and published by John Wiley & Sons. This book was released on 2013-03-04 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mechanical Vibration and Shock Analysis, Second Edition Volume 4: Fatigue Damage Fatigue damage in a system with one degree of freedom is one of the two criteria applied when comparing the severity of vibratory environments. The same criterion is also employed for a specification representing the effects produced by the set of vibrations imposed in a real-world environment. In this volume, which is devoted to the calculation of fatigue damage, the author explores the various hypotheses and models used to describe the behavior of material suffering fatigue and the laws of fatigue accumulation. He also considers the methods of counting response peaks, which are used to establish a histogram when it is impossible to use the probability density of the peaks obtained with a Gaussian signal. The expressions for mean damage and its standard deviation are established and other hypotheses are tested. The Mechanical Vibration and Shock Analysis five-volume series has been written with both the professional engineer and the academic in mind. Christian Lalanne explores every aspect of vibration and shock, two fundamental and extremely significant areas of mechanical engineering, from both a theoretical and practical point of view. The five volumes cover all the necessary issues in this area of mechanical engineering. The theoretical analyses are placed in the context of both the real world and the laboratory, which is essential for the development of specifications.

Book Synopsis High Cycle Fatigue by : Theodore Nicholas
Download or read book High Cycle Fatigue written by Theodore Nicholas and published by Elsevier. This book was released on 2006-07-07 with total page 656 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dr Theodore Nicholas ran the High Cycle Fatigue Program for the US Air Force between 1995 and 2003 at Wright-Patterson Air Force Base, and is one of the world’s leading authorities on the subject, having authored over 250 papers in leading archival journals and books. Bringing his plethora of expertise to this book, Dr Nicholas discusses the subject of high cycle fatigue (HCF) from an engineering viewpoint in response to a series of HCF failures in the USAF and the concurrent realization that HCF failures in general were taking place universally in both civilian and military engines. Topic covered include: Constant life diagrams Fatigue limits under combined LCF and HCF Notch fatigue under HCF conditions Foreign object damage (FOD) Brings years of the Author's US Air Force experience in high cycle fatigue together in one text Discusses HCF in the context of recent international military and civilian engine failures

Book Synopsis High-resolution Autoradiography by : George C. Towe
Download or read book High-resolution Autoradiography written by George C. Towe and published by . This book was released on 1954 with total page 692 pages. Available in PDF, EPUB and Kindle. 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.
