Experiments on shaped charge penetration into high and ultrahigh strength steel-fiber reactive powder concrete (RPC) targets were performed in this paper. Results show that the variation of penetration depth and crater diameter with concrete strength is different from that of shaped charge penetration into normal strength concrete (NSC). The crater diameter of RPC is smaller than that of NSC penetrated by the shaped charge. The jet particles are strongly disturbed and hardly reach the crater bottom because they pass through the narrow channel formed by jet penetration into the RPC. The effects of radial drift velocity and gap effects of jet particles for a shaped charge penetration into RPC target are discussed. Moreover, a theoretical model is presented to describe the penetration of shaped charge into RPC target. As the concrete strength increases, the penetration resistance increases and the entrance crater diameter decreases. Given the drift velocity and narrow crater channel, the low-velocity jet particles can hardly reach the crater bottom to increase the penetration depth. Moreover, the narrow channel has a stronger interference to the jet particles with increasing concrete strength; hence, the gap effects must be considered. The drift velocity and gap effects, which are the same as penetration resistance, also have significant effects during the process of shaped charge penetration into ultrahigh-strength concrete. The crater profiles are calculated through a theoretical model, and the results are in good agreement with the experiments.

本文进行了聚能弹药渗入高强度和超高强度钢纤维反应性粉末混凝土（RPC）目标的实验。结果表明，穿透深度和弹坑直径随混凝土强度的变化与异型药料渗入普通强度混凝土（NSC）的变化不同。RPC的弹坑直径小于被成形炸药穿透的NSC的弹坑直径。射流颗粒会受到强烈干扰，几乎不会到达火山口底部，因为它们会穿过由射流穿透进入RPC形成的狭窄通道。讨论了径向形变速度和射流粒子的间隙效应对聚能电荷穿透RPC目标的影响。此外，提出了一个理论模型来描述成形装药对RPC目标的渗透。随着混凝土强度的增加，抗穿透性增加，并且入口火山口直径减小。考虑到漂移速度和狭窄的弹坑通道，低速射流颗粒很难到达弹坑底部以增加穿透深度。此外，随着混凝土强度的提高，狭窄的通道对射流颗粒的干扰更强。因此，必须考虑差距效应。漂移速度和间隙效应与抗穿透性相同，在定型炸药渗入超高强度混凝土的过程中也具有显着影响。通过理论模型计算出弹坑轮廓，其结果与实验结果吻合良好。考虑到漂移速度和狭窄的弹坑通道，低速射流颗粒很难到达弹坑底部以增加穿透深度。此外，随着混凝土强度的提高，狭窄的通道对射流颗粒的干扰更强。因此，必须考虑差距效应。漂移速度和间隙效应与抗穿透性相同，在定型炸药渗入超高强度混凝土的过程中也具有显着影响。通过理论模型计算出弹坑轮廓，其结果与实验结果吻合良好。考虑到漂移速度和狭窄的弹坑通道，低速射流颗粒很难到达弹坑底部以增加穿透深度。此外，随着混凝土强度的提高，狭窄的通道对射流颗粒的干扰更强。因此，必须考虑差距效应。漂移速度和间隙效应与抗穿透性相同，在定型炸药渗入超高强度混凝土的过程中也具有显着影响。通过理论模型计算出弹坑轮廓，其结果与实验结果吻合良好。因此，必须考虑差距效应。漂移速度和间隙效应与抗穿透性相同，在定型炸药渗入超高强度混凝土的过程中也具有显着影响。通过理论模型计算出弹坑轮廓，其结果与实验结果吻合良好。因此，必须考虑差距效应。漂移速度和间隙效应与抗穿透性相同，在定型炸药渗入超高强度混凝土的过程中也具有显着影响。通过理论模型计算出弹坑轮廓，其结果与实验结果吻合良好。
