【 摘 要 】

In this paper, the impact experiments of steel fiber reinforced concrete with same impact velocity and different steel fiber contents are processed by one-stage light gas gun. Through the manganin gauges embedded in the target, the voltage-time signals are recorded. Lagrangian method is used to analyze the flow field, then the particle velocity (u), specific energy, specific volume withtimeare obtained. Moreover, it was observed from the measured pressure-time curves that the decay factor is smaller in the steel reinforced high strength concrete. The dynamic response is analyzed.
