In 1856, Lord Kelvin observed that metallic conductors subjected to mechanical strain exhibit a change in their electrical resistance. Since that time, engineers have attempted to measure and quantify ...

The Model 3442AVG is an all-purpose averaging axial extensometer which is used in compression or tension in order to measure Young’s modulus, offset yield, and strain to failure. It is both ...

Strain gauge sensors measure the strain (displacement) of an object under an applied force. When they are adhesively attached to the object under stress (an applied force), they deform with the object ...

Many conventional strain gages are similar in appearance to Figure 1. A serpentine pattern etched into a metal foil creates a relatively high resistance in a small space. The foil is bonded to a thin ...

High-temperature thin film strain gauges have emerged as indispensable tools in monitoring the mechanical integrity of critical components operating under extreme thermal conditions. Through the ...

When designing an experiment or test, simplicity is important. Each process added to a test or experiment to obtain data increases the potential for error. For ...

Measuring strains during mechanical testing can be challenging, particularly when initially developing the capability. Additionally, there are multiple strain measurement methods to choose from, each ...

MALVERN, Pa.--(BUSINESS WIRE)--The Micro-Measurements ® brand of Vishay Precision Group, Inc. (NYSE: VPG) (www.micro-measurements.com), industry experts in the design, development, and manufacture of ...

When used for materials testing, extensometers are used to accurately measure material properties that are critical for a vast range of engineering designs - aircraft, energy systems, medical devices, ...

The levels of mechanicalstrain most typically measured with strain gauges are very small and precise.Consequently, changes in resistance are also very small and thus cannot bemeasured directly with an ...
