Abstract

We have accumulated practically all the information available in the literature regarding empirical models used for describing high-speed normal penetration of rigid strikers into concrete shields, including recently posed models. The description of the models is unified; this includes recommendations on the range of applicability of the models and additional restrictions implied by the used mathematical formulations. The description of the models is quite comprehensive, and allows their direct application. All the relevant formulas are presented in SI units. In addition to this extensive survey we include the results of original comparative investigations on the performance of various models for describing penetration into semiinfinite and finite-thickness shields.
