Strain Gages on Composites—Gage-Selection Criteria
1989Selection of the proper strain gage is one of the first steps toward a successful test. The test material, the test environment, and the goals of the strain-gage survey must all be considered when choosing a strain gage, as well as the total cost of the gage installation.

Using strain gages to measure both strain and temperature
Experimental Mechanics, 1992A transducer is proposed that measures both temperature and strain by using two different strain gages. The theoretical basis for designing such a transducer is developed. Experimental results indicate that the temperature signal can be measured satisfactorily.

SCRATCH STRAIN GAGE EVALUATION
1969Abstract : The test results on the evaluation of the Prewitt Scratch Strain Gage are presented in the report. The test program was twofold: (1) observation of the gage operation under various strain applications and (2) investigation of strain recording sensitivity and measurement.

Electrical Resistance Strain Gages
2021An electrical resistance strain gage is a resistor used to measure strain. In its basic form, it is a wire adhered onto the surface of a component so that strains of the component are transmitted to the wire. Its operation is based on the discovery made by Lord Kelvin in 1856 that the electrical resistance of a wire increases with increasing strain and

1989
Conventional metallic-foil, electric-resistance strain gages are very popular for measuring surface strains and even internal strains (via embedded gages) in composites as well as metals. However, certain composites, notably soft biological tissues and tire cord-rubber, exhibit so little stiffness, due to their highly compliant matrix material, that ...

7th Aerodynamic Decelerator and Balloon Technology Conference, 1981
This paper describes the development of a unique strain measuring device which is intended to monitor the state of strain in thin balloon films during flight. The gate is bonded directly to the film without significantly altering the state of strain or stress in the wall of the balloon.

Experimental Techniques, 1988
The history and current status of thick-film strain gage technology are briefly reviewed, and data are presented on the performance characteristics of six different types of bonded piezoresistive strain gages. It is shown that the gage factor/thermal sensitivity characteristics make the thick-film strain gage technology attractive for general purpose ...

Fundamental Strain-Gage Technology
1989In 1856 Lord Kelvin reported that the resistance of copper and iron wires increased when subjected to a tensile strain1. This basic discovery has ultimately led to the development of the modern resistance foil strain gage. The ‘birthdate’ of the strain gage is considered to be 1938, when Ruge and Simmons, working independently, each measured strains ...
