In component and materials testing, extensometers are used in many different applications. Consequently, the technical needs for these devices are many and diverse, meaning that there is no single ...

Sensor-arm extensometers are used for performing compression, tensile, cyclic, and flexure tests. It is feasible to infinitely adjust the gage length to be suitable to the specimen to be tested.

Instron (Norwood, Mass., U.S.) is releasing the AVE3, an noncontacting video extensometer that delivers precise strain measurement with micron-level accuracy for tensile, compression and bend testing.

The Video Gauge noncontact extensometer from Imetrum (Bristol, UK) reportedly is the only device of its kind to achieve the exacting requirements of ISO 527-1: 2012 ASTM D638 equivalent. The system, ...
