Simple Models For Penetration Of Thick Targets
By Rigid Projectiles

Abstract
This paper discusses the material characteristics that influence resistance of thick
targets to penetration by rigid projectiles and critically reviews simple analytical
models for predicting the time history of the impact force and other response
variables over a practical range of impact energies. The scope of the reviewed
analyses is enhanced by accounting more rigorously for the contact geometries
and introducing empirical relations for the parameters adopted in the simplified
models. The analyses are implemented through a computer code whose
effectiveness and reliability are tested on realistic impact events from the
relevant technical literature. Comparisons are also made with finite element
results. It is thus shown that the shock loading on a structure and its appendices
can be reliably and efficiently predicted by a simple penetration analysis.
Various means of enhancing the scope and effectiveness of the model are
suggested.
Keywords: impact, projectile, penetration, cavitation, modelling.
