The Experimental layout is shown in Fig. Therefore, c5 was suitable for resisting multiple penetrations and absorbing shock wave. There was too little mortar in c5, because of weak combination of mortar and coarse aggregate, the crater surface bypassed all the coarse aggregate Fig. The appropriate propellant was chosen to burn completely in the bore, which could reduce the instability of the initial velocity, and avoid the image overexposure by the high speed camera. In this paper, penetration experiments of ogive-head long-rod projectile penetrating into concrete with different coarse aggregate content were performed.
V is the instantaneous velocity of the projectile.

The stress analysis in this section shows that R s is an inherent property of the mortar and is not affected by the volume fraction of the coarse aggregate. When the coarse aggregate volume fraction is less than Simplify the effect of voids volume fraction on the decrease of the static resistance stress is linear: Because c5 had no radial cracks, it was difficult to identify the boundary of the loose zone. Modeling on mass abrasion of kinetic energy penetrator. The effect of the maximum aggregate size on the penetration resistance and the fragments size distribution of thin target were studied by Werner et al. The target diameter was 0.
