Hammond and co-workers, (SCCM, 2003, p1125), measured the resistance change of lateral manganin gauges mounted in mild steel samples. All of the experiments were conducted at an impact velocity of 400m/s giving a shock pressure of {approx}7GPa. The results provide data from which the strength of the sample material at a shock pressure of {approx}7GPa can be derived. The analysis is simplified by assuming that the polymer in which the gauge is mounted has no strength. First, calibration curves obtained by previous workers for longitudinal gauges were used to estimate the pressure in the polymer surrounding each gauge corresponding to its measured resistance change. Hydrocode simulations were then used to determine the material strength that matched the observed polymer pressures at the gauge positions. An elastic-perfectly plastic model was assumed for both the sample and the manganin.
