An instrumented strain strainer tree for studies under multiaxial loading.

In addition, despite its many advantages, photomechanics has not yet fully replaced strain gauges and thermocouples.

Finally, by exciting an instrumented ring of strain gauges with an impact hammer and then with a piezo-actuator, the functionality of the method is proven.

A first objective of the test will be to test the sensitivity of detection and location by optical and electrical strain gauges placed on the surface of the specimen in comparison with the acoustic emission.

Using Global Positioning System, borehole tiltmeters, and borehole strainmeters to measure minute changes in deformation at Yellowstone, David Mencin and Glen Mattioli said:

Four pairs of gauges are used to show the uniformity of deformations in the direction of traction.

Another way to record the deformation development is to use strain gages (SG), applied to the UHPC test specimen.

Four pairs of gauges in a cross-section are used to show the distribution of the deformations (the neutral fiber), as well as a fifth pair of gauges placed in another section.

These deformations were verified by strain gages applied directly to the test specimen.

'Vacuum pressure gauges' include Pirani Gauges, Penning Gauges and Capacitance Manometers.

The strain gauges (2) are arranged on the deformation bodies (4) and capture the shear strain acting between the hinges (6) and load output plates (5).
