Instron (Norwood, MA, US) has introduced a new video extensometer, the AVE 2, that conforms to testing standards ISO 527, ASTM D3039 and ASTM D638. This second-generation advanced video extensometer is described as a fully-integrated device that adapts to the normal fluctuations of environmental conditions in the lab and can be adapted to any testing machine on the market that uses a ±10V analog input (performance depends on the system). Designed to reduce errors from thermal and lighting variations that are common in most labs, the AVE 2 uses a real-time 490-Hz data rate with 1-micron accuracy. The AVE 2 measures modulus and strain to failure of almost any material including composites, plastics, metals, textiles, films, bio-materials and more.
Editor PickA better method of structural health monitoring?
Fibersail, a 2014 startup firm with offices in Rotterdam, The Netherlands and Leça de Palmeira, Portugal, aims to change the current state of real-time structural health/shape monitoring for composite structures — initially, for wind farm operators.
