Experimental and numerical high-velocity impact studies of high-performance fiber reinforced concrete

In this work, we present a comprehensive experimental and numerical study of high-velocity impact with high-performance fiber reinforced concrete (HPFRC) targets and samples. A large data set from projectile impact tests with finite and semi-infinite targets and planar plate impact (PPI) tests is provided. This includes residual velocities, depths of penetration, qualitative and quantitative damage of perforated targets as well as free surface velocity time curves from PPI. Moreover, we derive a hydrocode simulation model for HPFRC from material characterization results, literature sources, and some results of the given impact data set. The good performance of this model is demonstrated by a simultaneous reproduction of the experimental residual projectile velocities, qualitative target damage patterns, and surface velocity time curves. In two additional model applications, damage quantities of perforated targets and depths of penetration from semi-infinite targets are investigated. In these application cases, the experimental data is reproduced by the derived simulation model with reasonable accuracy.
