strain gauge

A very fine wire or thin foil which exhibits a change in resistance proportional to the mechanical strain imposed on it; usually mounted on or bonded to some type of carrier material or wound on a jig or fixture; used in the experimental determination of stresses.

For such strain measurement resistive strain gauges along with unbalanced Wheatstone bridge circuits are widely used [5].
One of the benefits of using the image correlation photogrammetry technique is that it gives the strain readings of large-scale elements in a short time without any limitation of ultimate strain capacities, unlike strain gauges. A number of research studies are using image correlation photogrammetry to calculate the strain distribution on special structural components and joints (Al-Mosawe, Al-Mahaidi, and Zhao 2016a; Lee and Al-Mahaidi 2008; Al-Mosawe, Al-Mahaidi, and Zhao 2016b; Al-Mosawe, AlMahaidi, and Zhao 2015).
The resistance increments of the strain gauges [[epsilon].sub.1], [[epsilon].sub.2] were imposed by a mechanism deflecting the beam with the use of a micrometer screw gauge and providing a good repetitiveness of the deflections (Fig.
Trials undertaken compared the results of dummy test coupons, instrumented with both strain gauges against laser-system markers and calibrated extensometers.
Stress measurements were carried out using 2 mm long, 120 [OMEGA] foil type strain gauges, and an ac strain gauge bridge.
The basic issue of measuring with strain gauges is to locate them properly on the structure.
Strain gauges typically measure very small and precise mechanical strain.

During calibration, the distance between the clamp and the rotary actuator and the distances between the strain gauges and interface between the bars were maintained the same.
So Clark and team at Unimelb tore down a Wii balance board and hacked into its strain gauges and accelerometers to tap into their raw data.
