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