Practical Residual Stress Measurement Methods


Book Description

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




Technology and Practical Use of Strain Gages


Book Description

This book is a profound compendium on strain gages and their application in materials science and all fields of engineering. It covers both the theoretical and practical aspects of strength and stress analysis using the technique of strain gages. A brief historical review about strain gage inventions is looking at the "who, when and how". The comprehensive bibliography leads to additional background information. Particular consideration is given to the stress analysis in order to verify the mechanical properties and capacity of components with focus on stability and serviceability, optimization, and safety checks, as well as in order to foresee inspection and monitoring. The practice-oriented descriptions of the principles of the measurement, installation and experimental set-ups derives from the authors own experiences in the field. Particular emphasis is laid on the correct planning and assessment of measurements, and on the interpretation of the results. Step-by-step guidance is given for many application examples, and comments help to avoid typical mistakes. The book is an indispensable reference work for experts who need to analyze structures and have to plan measurements which lead to reliable results. The book is instructive for practitioners who must install reliable measurement circuits and judge the results. The book is also recommended for beginners to get familiar with the problems and to learn about the possibilities and the limits of the strain gage technique.
