Stress Measurements using strain gauges (strain gage) are needed to validate design of a structure and to ensure that the structure is able to withstand designed load. While most of the structural stresses are readily predicted using Finite Elements, it is necessary to do strain gauging and measure the actual stress/strain at the areas that are difficult or impossible to plausibly simulate. Such locations typically include welds, critical load bearing members with intricate geometries, and uncertain load distribution etc. Tension, compression, shear and torsional stresses can be measured with strain gauges by accurately determining the actual material strain or deformation. Strain gauges are constructed from resistive material that exhibits linear change in resistance with respect to deformation. Most strain gauges are able to linearly measure deformation within 2-3% of strain, or 0.02 strain units. Careful arrangement of multiple gauges in wheatstone circuit, called wheatstone bridge, gives measurable output voltage corresponds to the change in resistance. Changes of fraction of ohms produce millivolts of signal to be measured with sensitive data acquisition systems. imc Data Acquisition Systems are equipped…
