Available in PDF, EPUB and Kindle. Book excerpt: Failures of many mechanical components in service result from fatigue. The cracks which grow may either originate from some pre-existing macroscopic defect, or, if the component is of high integrity but highly stressed, a region of localized stress concentration. In turn, such concentrators may be caused by some minute defect, such as a tiny inclusion, or inadvertent machining damage. Another source of surface damage which may exist between notionally 'bonded' components is associated with minute relative motion along the interface, brought about usually be cyclic tangential loading. Such fretting damage is quite insidious, and may lead to many kinds of problems such as wear, but it is its influence on the promotion of embryo cracks with which we are concerned here. When the presence of fretting is associated with decreased fatigue performance the effect is known as fretting fatigue. Fretting fatigue is a subject drawing equally on materials science and applied mechanics, but it is the intention in this book to concentrate attention entirely on the latter aspects, in a search for the quantification of the influence of fretting on both crack nucleation and propagation. There have been very few previous texts in this area, and the present volume seeks to cover five principal areas; (a) The modelling of contact problems including partial slip under tangentialloading, which produces the surface damage. (b) The modelling of short cracks by rigorous methods which deal effectively with steep stress gradients, kinking and closure. (c) The experimental simulation of fretting fatigue.
Download or read book Fretting Fatigue Testing Methodology Incorporating Independent Slip and Fatigue Stress Control written by D. Werner and published by . This book was released on 2000 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: A fretting fatigue apparatus was designed, built and tested incorporating independent computer control of fretting fatigue slip distance and fatigue stress. This was accomplished through the utilization of two coaxial servo-hydraulic test actuators controlled in real time by computer. The central hydraulic actuator applies the fatigue load to the test specimen, while the outer concentric hydraulic actuator moves the fretting pin carrier apparatus. Independent control of slip displacement is achieved with the use of a capacitance displacement gage attached to the specimen fret pin carrier in such a manner that relative displacements of

Book excerpt: The intrusion of fretting fatigue in the field of flight structures has been responsible, in many cases, for the high strength reduction factors, of 10 or more, commonly encountered. Consequently, a primary objective of the report was to consider the evidence to support the claim that fretting must be ranked in importance with geometric stress concentration and the like, when considering the fatigue behaviour of structures. Thus, Mean Structures Curves, Crack Propagation And Non-Propagating Cracks and some Fundamental Fretting Fatigue Researches have been described and interpreted with the elucidation of the fretting fatigue mechanism in mind. A survey of certain Anti-Fret Techniques has been included not only to emphasize the gains to be made in terms of structural efficiency but to justify the main thesis that Primarily, the fretting fatigue mechanism is controlled by the stress fields generated by the contact of two surface topographies.

Download or read book Determination and Control of Contact Pressure Distribution in Fretting Fatigue written by K. Sato and published by . This book was released on 1992 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contact pressure is one of the most important factors in fretting fatigue. The contact pressure distribution on loading of applied cyclic stress is markedly different from that on unloading. To elucidate the effect of contact pressure on fretting fatigue strength, the contact pressure distribution should be exactly determined. In this paper, the contact pressure distribution was calculated by using a boundary element method and monitored by an experimental method of caustics. Differences in the contact pressure distribution between the shapes of fretting bridges whose height is 10, 15, 20, and 30 mm at a constant span of 30 mm, and between two types of clamping, which are center clamping and edge clamping at the back face of the bridge, were analyzed. In order to examine the effect of the contact pressure distribution on the fretting fatigue strength, fretting fatigue tests in plane bending were carried out. The S-N properties obtained from fretting fatigue tests could be estimated analytically by equivalent stress amplitude.

Available in PDF, EPUB and Kindle. Book excerpt: This book, which has only one very distant forerunner authored by David A. Hills with David Nowell, represents a very big step that is the quantification of these problems and represents the twenty-five years' worth of work which have gone on at Oxford since the first book on the subject. Fatigue (popularly 'metal fatigue') is the primary failure mode of all machines, engines, transmissions and indeed almost all mechanical devices. The propagation of cracks is well understood and is treated in the subject Fracture Mechanics. By contrast, the nucleation of cracks is very hard to quantify and this remains the case with so-called 'free initiation' and, to a lesser extent, at cracks nucleated from stress raising features. But the third form of nucleation, where cracks start from the edges of rubbing components, that is, at joints, is potentially a very much better-defined environment, and therefore, the problem is amendable to attack by applied mechanics and experiment. The contents are of value both to those embarking on research on the subject and to practitioner in industry.

Download or read book The Theory of Critical Distances written by David Taylor and published by Elsevier. This book was released on 2010-07-07 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: Critical distance methods are extremely useful for predicting fracture and fatigue in engineering components. They also represent an important development in the theory of fracture mechanics. Despite being in use for over fifty years in some fields, there has never been a book about these methods – until now. So why now? Because the increasing use of computer-aided stress analysis (by FEA and other techniques) has made these methods extremely easy to use in practical situations. This is turn has prompted researchers to re-examine the underlying theory with renewed interest. The Theory of Critical Distances begins with a general introduction to the phenomena of mechanical failure in materials: a basic understanding of solid mechanics and materials engineering is assumed, though appropriate introductory references are provided where necessary. After a simple explanation of how to use critical distance methods, and a more detailed exposition of the methods including their history and classification, the book continues by showing examples of how critical distance approaches can be applied to predict fracture and fatigue in different classes of materials. Subsequent chapters include some more complex theoretical areas, such as multiaxial loading and contact problems, and a range of practical examples using case studies of real engineering components taken from the author’s own consultancy work. The Theory of Critical Distances will be of interest to a range of readers, from academic researchers concerned with the theoretical basis of the subject, to industrial engineers who wish to incorporate the method into modern computer-aided design and analysis. Comprehensive collection of published data, plus new data from the author's own laboratories A simple 'how-to-do-it' exposition of the method, plus examples and case studies Detailed theoretical treatment Covers all classes of materials: metals, polymers, ceramics and composites Includes fracture, fatigue, fretting, size effects and multiaxial loading
