Abstract
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.
