Abstract

A simple experimental method was introduced to study the mechanical properties of reinforced concrete under shock loading. The one-stage light gas gun was used to test the mechanical properties of reinforced concrete with different reinforcement ratios under various impact velocities. Three Mn-Cu piezoresistive pressure gauges embedded in the target were used to record the voltage-time signals, from which the stress-strain curves of reinforced concrete were obtained using Lagrangian analysis. Experimental results indicated that the load-bearing capacities of reinforced concrete increased greatly with the impact velocity and the reinforcement ratio. The peak stress of the shock wave decreased exponentially with the propagation distance.

    Ning et al. [31] proposed a new coupled three-dimensional Euler–Lagrange method to calculate projectile penetration into reinforced concrete slabs, obtained the fragment behavior laws of concrete slabs under different scenarios, and compared the calculation results with experimental data to verify the effectiveness of the new numerical method. Ning et al. [32,33] conducted a long-term study on a constitutive model of concrete materials under different strain rates. The stress–strain curves of concrete materials under low strain rates were obtained through quasi-static uniaxial compression experiments, and the failure mode and mechanism of the concrete material were analyzed.
