The behavior of typical corner supported bare and bonded poly-film hardened concrete plates are investigated experimentally using an Instron impact testing machine and evaluated numerically using two well-known phenomenological models of concrete. Before use, the models are critically evaluated and necessary modifications are incorporated. After validation with experimental data the better of the two models was selected and a series of simulations on the impact resistance of bare as well as the ones with bonded poly-film reinforcement to back face only as well as to both faces of the plate are undertaken with increasing magnitudes of impact energy to study the performance under progressively severe impact energy to evaluate the relative effectiveness of different options of the hardening scheme. Based on this study, the effectiveness of the proposed bonded poly-film based hardening scheme is established.

硬化角支撑混凝土板的抗冲击性能


使用 Instron 冲击试验机对典型角支撑裸露和粘合聚膜硬化混凝土板的行为进行了实验研究，并使用两种著名的混凝土唯象模型进行了数值评估。在使用之前，会对模型进行严格评估并进行必要的修改。经过实验数据验证后，选择了两个模型中较好的一个，并对裸露的以及仅在板的背面和两面粘合聚膜增强材料的抗冲击性进行了一系列模拟随着冲击能量的增加，研究在逐渐严重的冲击能量下的性能，以评估硬化方案的不同选项的相对有效性。基于这项研究，建立了所提出的基于粘合聚膜的硬化方案的有效性。
