Abstract
The dynamic modulus of elasticity (MoE) of concrete can be determined by measuring the natural frequency and vibration damping of the concrete under dynamic loading. This paper is to determine the dynamic modulus of elasticity of concrete subjected to different pressure of high impact load using split Hopkinson pressure bar. Piezoelectric accelerometer is used to detect the vibration of concrete in the pressure bar system. The accelerometer is placed on the concrete specimen surface to measure the direct vibration of concrete and the fundamental frequency is determined by analyzing the wave signal. The results shows that the fundamental frequency of the concrete increase when the high impact pressure load of increase. The theoretical relationship that relates the fundamental frequency with the modulus of elasticity is used to calculate the MoE of concrete. Calculation shows that the dynamic modulus of concrete is enhanced with the increase of the fundamental frequency of the concrete specimen due to increasing high impact load
