HBM seems mostly to have switched to gauge, despite the fact that their incredibly thorough book "An Introduction to Measurements using Strain Gages" uses gage. It is now available as a free .pdf from the HBM website under the title "An Introduction to Stress Analysis and Transducer Design using Strain Gauges", but the only change from gage to ...
An unmounted resistive foil strain gauge. A strain gauge takes advantage of the physical property of electrical conductance and its dependence on the conductor's geometry. . When an electrical conductor is stretched within the limits of its elasticity such that it does not break or permanently deform, it will become narrower and longer, which increases its electrical resistance end-to-
Stress–strain analysis (or stress analysis) is an engineering discipline that uses many methods to determine the stresses and strains in materials and structures subjected to forces. In continuum mechanics , stress is a physical quantity that expresses the internal forces that neighboring particles of a continuous material exert on each other ...
A strain gauge sensor measures the deformation of the elastic element, and the output of the sensor is converted by an electronic circuit to a signal that represents the load. Capacitive strain gauges measure the deformation of the elastic material using the change in capacitance of two plates as the plates move closer to each other.
Arthur Claude Ruge (pronounced ROO-gee; July 28, 1905 – April 3, 2000) was an American mechanical engineer and inventor who developed and pioneered the modern bonded wire resistance strain gauge.
A tensile specimen usually has a standardized sample cross-section. It has two shoulders and a gauge (section) in between. The shoulders and grip section are generally larger than the gauge section by 33% [4] so they can be easily gripped. The gauge section's smaller diameter also allows the deformation and failure to occur in this area. [2] [5]
The Hopkinson pressure bar was first suggested by Bertram Hopkinson in 1914 [1] as a way to measure stress pulse propagation in a metal bar. Later, in 1949 Herbert Kolsky [2] refined Hopkinson's technique by using two Hopkinson bars in series, now known as the split-Hopkinson bar, to measure stress and strain, incorporating advancements in the cathode ray oscilloscope in conjunction with ...
Edward E. Simmons Jr. (1911 in Los Angeles, California – May 18, 2004, in Pasadena, California) was an electrical engineer and the inventor of the bonded wire resistance strain gauge. Simmons attended the California Institute of Technology, where he received a B.S. in 1934 and an M.S. in 1936. He continued to work for the Institute under ...
