Abstract
An extensometer for measuring strain in a test specimen is disclosed. The extensometer includes a frame and a flexible support structure, preferably, a loop, mounted to the frame. A measuring device is mounted to the flexible support loop at a position spaced apart from the frame and engages a surface of the specimen with a selected amount of contact force. The measuring device provides an output signal proportional to the measured strain.
