Residual stresses (RS) are stresses present inside materials even in the absence of any applied load. They are of capital importance because they can impact greatly on the mechanical strength of the material, on its dimensional correspondence to design specifications as well as on the fatigue life of the part. RS measurement and evaluation is currently an important research topic where a lot of challenges still need to be addressed. This book aims to provide the reader with an overview of the principal novelties in this field including current limitations and potential future developments. Both radically new experimental approaches as well as recent evolutions of consolidated ones will be presented, along with the latest novelties in the area of numerical residual stress evaluation.

An introductory and intermediate level handbook written in pragmatic style to explain residual stresses and to provide straightforward guidance about practical measurement methods. Residual stresses play major roles in engineering structures, with highly beneficial effects when designed well, and catastrophic effects when ignored. With ever-increasing concern for product performance and reliability, there is an urgent need for a renewed assessment of traditional and modern measurement techniques. Success critically depends on being able to make the most practical and effective choice of measurement method for a given application. Practical Residual Stress Measurement Methods provides the reader with the information needed to understand key residual stress concepts and to make informed technical decisions about optimal choice of measurement technique. Each chapter, written by invited specialists, follows a focused and pragmatic format, with subsections describing the measurement principle, residual stress evaluation, practical measurement procedures, example applications, references and further reading. The chapter authors represent both international academia and industry. Each of them brings to their writing substantial hands-on experience and expertise in their chosen field. Fully illustrated throughout, the book provides a much-needed practical approach to residual stress measurements. The material presented is essential reading for industrial practitioners, academic researchers and interested students. Key features: • Presents an overview of the principal residual stress measurement methods, both destructive and non-destructive, with coverage of new techniques and modern enhancements of established techniques • Includes stand-alone chapters, each with its own figures, tables and list of references, and written by an invited team of international specialists

This book presents the proceedings of the International Conference on Residual Stresses 10 and is devoted to the prediction/modelling, evaluation, control, and application of residual stresses in engineering materials. New developments, on stress-measurement techniques, on modelling and prediction of residual stresses and on progress made in the fundamental understanding of the relation between the state of residual stress and the material properties, are highlighted. The proceedings offer an overview of the current understanding of the role of residual stresses in materials used in wide ranging application areas.

This manual has been assembled as a ready reference source for the engineer who must measure residual stresses. Although the literature has abundant information on the individual methods of residual stress measurement, this manual is unique in that most of the useful methods have been selected, described, classified, and compared.Methods of measuring residual stress may be classified as mechanical, physical, or chemical. Mechanical methods that are most widely used involve the machining of the part to release the residual stresses. These methods are considered in detail and occupy the bulk of this manual.Of the physical methods, x-ray diffraction has many advantages in solving some residual stress problems. One of the major advantages is that it is completely nondestructive if only surface residual stresses are desired. This method is briefly described and its limitations discussed so that the investigator may choose this method if it fulfills his needs. The method and the necessary techniques have been covered in detail in Ref. 1.Of the chemical methods, the stress corrosion cracking technique seems to be the most useful. This cracking is known to be dependent upon the surface tensile stress level. At present it is only a qualitative measure of the stress, but perhaps at some future date, quantitative chemical methods may be developed.To make residual stress measurements, the engineer must: 1Select the most appropriate method. 2Completely familiarize himself with the theory behind the method chosen. 3Learn the techniques of measurement used by previous investigators.Note that the word "method" is reserved to mean the individual category of stress analysis, and that "technique" applies to the experimental procedure.The choice of the method depends to a large extent upon the geometry of the specimen, the precision desired, the type and location of the stress it is desired to measure, and the equipment available. The numerous mechanical methods available are classified into four groups. These are: the parting-out method, the layer removal method, the boring and turning method, and the hole drilling method. The nonmechanical x-ray method is briefly discussed here for comparison.Once the method has been selected, measurements should not be taken and their values blindly substituted into equations. Each term in the expressions relating the deformation to the residual stress should be completely understood and the sign convention used for these terms should be well known. For this reason, a derivation for each method has been included with the necessary assumptions and limitations. Following a study of these equations, it may be decided whether some automatic or computer technique should be used. In some instances in which a large number of specimens are to be analyzed, the computer technique offers obvious advantages. At this point, it is also necessary to determine the precision with which the stresses are to be determined. This, of course, can be related directly to the precision used in the measurement of the deformation changes and the original dimensions of the specimen itself.The correct choice of the many and varied techniques for measuring dimensional changes used in the determination of residual stress is extremely important if accurate and reproducible data are to be obtained. Machining stress introduced in dissecting must not be larger or more significant than the stress that is to be measured. The techniques used to remove material are numerous, and some of the better currently used techniques are considered. The specific techniques associated with any particular method are included and special fixtures and procedures are described and sample calculations are given.

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.
