SOIL STRAIN GAGE INSTRUMENTATION

Journal of Terramechanics, 1966
Soil strain gage instrumentation was developed for the measurement of static and dynamic strains when embedded in soil. The gage is suitable for both laboratory and field application. The strain sensor consists of two mechanically uncoupled flat-coil disks which are embedded in the soil in near parallel and concentric orientation.

Photoelastic strain gages

Experimental Mechanics, 1961
New photoelastic strain gages are described which are self-contained and give an accurate direct indication of magnitudes and directions of principal stresses. Large numbers of gages may be observed simultaneously and critical areas of members may be readily located.

Strain Gage Installation Tool

Experimental Techniques, 1980
This paper describes the development of a tool designed to spot weld Ailtech strain gages to the inside surface of small diameter tubing. Fundamental spot welding techniques are discussed with emphasis placed upon the adaptations that were necessary to attach a gage that was neither visually nor physically accessible to the installer.

Piezoelectric strain rate gages

The Journal of the Acoustical Society of America, 1991
Piezoelectric strain rate gages have been designed using linear piezoelectric theory and relatively simple circuitry that can be used to measure an average strain rate at a point of a structure. By combining the effective surface electrode, appropriate skew angle and the correct polarization profile, a uniaxial strain rate gage that measures only the ...

Modified Soil Strain Gage

Journal of the Geotechnical Engineering Division, 1977
While it appears that the greatest effort regarding in-situ monitoring of soils has been directed as stress measurements, strain monitoring is of equal importance. The reason for the past emphasis on stress measurement is obviously due to inherent difficulties associated with strain measurements in a discrete particulate mass such as soil.
