This book was released on 2006 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents novel applications of the deep-hole drilling technique for residual stress measurement in components. The results outline the versatility of this technique for application in complex situations such as residual stress measurement in very thick components, components with difficult access to the measurement location, very large components, components requiring high spatial resolution, and components requiring detailed near surface residual stress distribution. The deep-hole drilling measurements were compared with results obtained using other measurement techniques. Excellent agreement was found between the results.

Download or read book Hole Drilling Method for Measuring Residual Stresses written by Gary S. Schajer and published by Morgan & Claypool Publishers. This book was released on 2018-01-22 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the theory and practice of the Hole-Drilling Method for measuring residual stresses in engineering components. Such measurements are important because residual stresses have a "hidden" character because they exist locked-in within a material, independent of any external load. These stresses are typically created during component manufacture, for example, during welding, casting, or forming. Because of their hidden nature, residual stresses are difficult to measure and consequently are often ignored. However, they directly add to loading stresses and can cause catastrophic failure if not properly included during engineering design. Thus, there is an urgent need to be able to identify and measure residual stresses conveniently and reliably. The Hole-Drilling Method provides an adaptable and well-proven method for measuring residual stresses in a wide range of materials and component types. It is convenient to use and gives reliable results. Because of the hidden nature of residual stresses, the measurement method must necessarily be indirect, thus, additional care and conceptual understanding are necessary to achieve successful results. This book provides a practical introduction to the Hole-Drilling Method, starting from its historical roots and going on to focus on its modern practice. The various chapters describe the nature of residual stresses, the principle of hole-drilling measurements, procedures and guidance on how to make successful measurements, and effective mathematical procedures for stress computation and analysis. The book is intended for practitioners who need to make residual stress measurements either occasionally or routinely, for practicing engineers, for researchers, and for graduate engineering and science students.

Available in PDF, EPUB and Kindle. Book excerpt: The development of an effective method of drilling oil and gas wells to depths of 3-5 km and more is a complex problem of great practical interest. "Deep Hole Drilling With Explosives" is a distinctive and very interesting work of the engineer A. P. Ostrovskii, who more than twenty years ago, by his original suggestions, made a start in investigating the field of so-called non-bit processes of shattering rocks when drilling holes, a.nd, with his co-workers, developed a fundamentally new explosive method of drilling deep holes. This book discusses the new trend in worldwide a.pplication of explosives in technology and the national economy; it presents considerable experimental material on the effect of explosions in solid media, material that is not only interesting to specialists in mining but also to physicists. Many phenomena discussed by the author and cited in the book still await explanation, but the fact that these phenomena have been already subjected to experimental study undoubtedly adds to our knowledge of one of the most meagerly investigated areas of the science of explosions-concerning the shattering effect of explo sions on solid media. July 29, 1960 Professor M. A. Sadovskii Corresponding Member of the Academy of Sciences of the USSR 1 INTRODUCTION Together with the perfection of turbine drilling and the introduction of electrical drills in the USSR, new methods have been developed for shattering rock and drilling deep oil and gas wells without the use of a bit.

Download or read book Residual Stresses in Composite Materials written by Mahmood M. Shokrieh and published by Woodhead Publishing. This book was released on 2014-02-14 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: Residual stresses are a common phenomenon in composite materials. They can either add to or significantly reduce material strength. Because of the increasing demand for high-strength, light-weight materials such as composites and their wide range of applications in the aerospace and automotive industries, in civil infrastructure and in sporting applications, it is critical that the residual stresses of composite materials are understood and measured correctly. The first part of this important book reviews destructive and non-destructive testing (NDT) techniques for measuring residual stresses. Various mathematical (analytical and numerical) methods for calculation of residual stresses in composite materials are also presented. Chapters in the first section of the book discuss the simulated hole drilling method, the slitting/crack compliance method, measuring residual stresses in homogeneous and composite glass materials using photoelastic techniques, and modeling residual stresses in composite materials. The second part of the book discusses residual stresses in polymer matrix, metal-matrix and a range of other types of composites. Moreover, the addition of nanoparticles to the matrix of polymeric composites as a new technique for reduction of residual stresses is discussed. Residual stresses in composite materials provides a comprehensive overview of this important topic, and is an invaluable reference text for both academics and professionals working in the mechanical engineering, civil engineering, aerospace, automotive, marine and sporting industries.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Deep Hole Drilling It is well known that a long, or deep, hole - that is, one long in proportion to its diameter - is best roughed out and finished by using a tool on the end of a long bar which enters the work from one end. This is true, whether drilling into solid metal, or boring and reaming a hole that has already been drilled or bored out. A boring bar which extends through the piece, and on which is either a stationary or a traveling head, is not satisfactory for very long work, owing to the spring and deflection of the bar, which is made worse by the fact that the bar must be enough smaller than the bore to allow room for the cutter head. While a long hole may sometimes be finished satisfac torily by means of such a boring bar, by packing the cutter head with wooden blocks which just fill the part of the bog that has been ma chined, and so support the bar, the method is fundamentally incor rect for long work.
