Numerous formulae are available for predicting the scabbing limit and perforation limit thicknesses subjected to impact loading, but no formula has yet been proposed for estimating the scabbing depth, which is the damaged depth at the rear face when the back of the concrete panel is peeled. In this paper, a new energy-based impact formula along with a theoretical background is proposed to estimate the scabbing depth, scabbing limit, and perforation limit. Based on the scabbing theory, energy–depth relation, and energy conservation law, the new formula is developed and verified with test results. Compared to other impact formulae, the proposed impact formula is found to be more effective.

基于能量的冲击公式的开发(第二部分):刮擦深度,刮擦极限和穿孔极限

可以使用许多公式来预测承受冲击载荷的刮擦极限和穿孔极限厚度,但是尚未提出用于估计刮擦深度的公式,该公式是当剥开混凝土面板背面时在背面的损坏深度。在本文中,提出了一种新的基于能量的冲击公式,并结合了理论背景来估算划痕深度,划痕极限和射孔极限。根据the理论,能量深度关系和节能规律,开发了新公式并通过测试结果进行了验证。与其他影响公式相比,发现建议的影响公式更为有效。
