A strain gage works to measure the amount of strain on a given object. At its most basic form, a strain gage converts a change in dimension to a change in electrical resistance. The ratio of mechanical strain to electrical resistance is what is known as the Gage Factor, and is specific to the type/lot of strain gage used. ...

The DEMEC Mechanical Strain Gauge was developed as a reliable and accurate way of taking strain measurements at different points on a structure using a single instrument. With a discrimination of two microstrains (on the 200 mm gauge) and gauge lengths of 50 to 2000 mm the DEMEC strain gauge is ideal for use on many types of structure for ...

The use of a strain gauge to measure loads is, in some respects, similar to its use in determining stress, but a different approach is required. In load measurement, it is necessary to compile a suitably selected configuration of strain gauges, which can be used to measure often very complex loads of the structure.

In order to measure strain with a bonded resistance strain gauge, it must be connected to an electric circuit that is capable of measuring the minute changes in resistance corresponding to strain. Strain gauge transducers usually employ four strain gauge elements that are electrically connected to form a Wheatstone bridge circuit.

The bonded semiconductor strain gauge was schematically described in Figures 2-4A and 2-4B. These devices represent a popular method of measuring strain. The gauge consists of a grid of very fine metallic wire, foil, or semiconductor material bonded to the strained surface or carrier matrix by a thin insulated layer of epoxy (Figure 2-5).

Because of the behavior of copper wire, and the general size relative to strain-gage-type rolled foil, this method suffers from two limitations: (a) the crack tip may progress considerably beyond the wire without breaking the strand, and (b) in areas of high cyclic strains, the wire may fail in fatigue without crack initiation in the specimen.
