Abstract

Extensive work has been carried out to investigate the effects of the impact of rigid
projectiles on concrete targets. Many of this research investigation have concluded with
presenting empirical formulae that correlate – to the best possible extent – some of the
variables of the phenomena with the results of the experimental work.
This paper presents a review on the validity and limitations of empirical formulae adopted in
the design of nuclear structures in USA and UK to predict a local impact effects in concrete
targets struck by hard projectiles. These formulae are used to determine the penetration depth,
scabbing thickness and perforation thickness of the concrete target. Failure mechanisms are
classified based primarily on experimental evidence. An energy approach and numerical
modeling with finite element for investigating the penetration of concrete by rigid missiles
and the associated phenomena are also presented.
Criticisms are made on the validity and limitations of the empirical formulae. The future
trend of the analysis and design of concrete penetration by hard missiles impact are predicted.
