The terminal effect in the reinforced concrete penetrated by a kinetic projectile is a main top-ic in the field of impact and defence engineering. The scale similarity law describing the penetration process in the reinforced concrete struck by a kinetic projectile was obtained by using the dimension analysis. Based on this scale similarity law, the. effect of rebar in the reinforced concrete during the penetration process was analyzed and the approach to establish an empirical formula to calculate the penetration depth was discussed. By considering the rebar effect and the scale similarity law, the I: I and 1-2.5 scale experiments and the 1-2.5 and I : 4 scale numerical simulations were carried out. comparing analyses show that the experimental results well accord with the scale similarity law. Final-ly, the scale relation for the penetration and perforation effects of reinforced concrete struck by the ki-netic projectile was expounded.
