Abstract
The calibration of manganin gauges for lateral stress measurements, in shock loaded specimens, is revisited through a simplified analysis, which is based on the dependence of the gauge's strength on shock amplitude. This dependence is derived from the measured resistive hysteresis of the gauge, as obtained in shock and release experiments. The resulting values for the gauge's strength, as a function of shock amplitude, are about half the values which were obtained previously by a different analysis. With the revised strength values, a new calibration curve is derived for the commercial grid-like gauges, as lateral stress transducers in planar impact experiments.
