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 author`s 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.
