Abstract

The influence of the overall structural response on the perforation of a concrete target is studied in this paper. The local perforation of the concrete target is idealized as a combined penetration and cone-plugging model. The overall structural response is simplified as an elastic, perfectly-plastic single degree of freedom (SDoF) model. A dimensional analysis is conducted to identify influential non-dimensional numbers in this problem to obtain non-dimensional governing equations. It is shown by parametric analyses that the overall stiffness and the overall strength of the concrete structure may influence the local perforation of the concrete target, which may help plan further experiments and numerical studies. The parameters introduced in the SDoF model can be obtained from actual concrete structures by using definitions of equivalent parameters, which has been generally accepted in dynamic structural analysis. © 2006 Elsevier Ltd.
