Abstract

The important characteristics and construction of the common types of extensometers are reviewed. Extensometers are the most convenient and widely used instruments for the measurement of strain in a material test specimen. Traditionally extensometers have been based around contacting techniques, however noncontacting optical techniques are becoming more important and the two approaches are compared in this chapter. Whichever technique is employed it is important to be aware of the possible influence of the extensometer on the test specimen and the need to match the extensometer to the specimen, environment, and test being carried out.
