Effectiveness of foil-shaped manganin gauge in pressure measurement of shock wave in solid.

Foil-shaped manganin gauges are used for pressure measurement of shock wave insolid. Some experiments of resistance change under shock pressure are made to discussthe effectiveness of their gauges as in-material gauge. The resistance changes aremeasured as a function of shock pressure. Shock waves are generated into solid bya single-stage gas gun. Shock pressure are obtained by using the impact velocity ofprojectile and the shock compression data of standard materials, such as copper, sapphireand fused quartz. The results by the foil-shaped manganin gauge used here arein good agreement with the ones under the static pressure, while the other results undershock pressure using manganin wire by other workers have been not in agreement withstatic data. It is concluded that the foil-shaped manganin gauge used here is very useful as in-material gauge for shock pressure measurement.
