Abstract
An extensometer measures strain on a test specimen subjected to tensile, compression or fatigue tests. The extensometer has a pair of members that are connected together preferably with at least two spaced-apart flexible plates. The members are coupled to move with the specimen when the specimen is subjected to the foregoing tests. A measuring device measures a change in distance of the members relative to each other in order to measure elongation or compression of the test specimen.
