Strain can be defined as the deformation of a material resulting from applied force, and it is measured by change in length. It can be either compressive or tensile. A strain gauge is a device that ...

Compared to traditional structural materials, polymer matrix composites (PMC) offer greatly enhanced performance and flexibility. However, these benefits come at the cost of increased material ...

I was one of the principal designers for the Lockheed Skunk Works flight test instrumentation group back in the late '70s through my retirement in 2008. Back around 1980, we were working toward the ...

“Gauging the strain,” February’s Special Report on Data Acquisition, presented traditional strain gage theory and highlighted several instruments and bridge amplifiers suitable for use with strain ...

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 ...

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 ...

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 ...

The most common device for the measurement of load, pressure, torque, and even piezo-resistive (low frequency) acceleration is the strain gauge transducer. As a transducer, which converts a measured ...
