Mechanical Behavior of Steel Fiber Reinforced Concrete Investigated by One-Stage Light Gas Gun Experiment

[摘要] This paper presents shock Hugoniot compression data for several concrete materials obtained from flat plate impact experiments. The manganin pressure gauge was used to measure the pressure-time curves of the samples. The physical quantities were all obtained by the Lagrange method. Moreover, it is observed from the measured pressure-time curves that the rate sensitivity of the dynamic response to the concrete is not negligible. Based on the polynomial Grüneisen equation, the parameters of the equation of state of concrete were obtained. The steel fiber reinforcement effect was analyzed.
