Abstract
The present study is dedicated to the reliability analysis of projectile penetration into a buried concrete target. The expressions for depths of penetration in the buried target have been derived for crater and tunnel regions separately using the methodology proposed by earlier investigators. These penetration depths have then been employed for subsequent reliability analysis using first-order reliability method. Design points, important for probabilistic design, have been located on the failure surface. Sensitivity analysis has been carried out to study the influence of various random variables on projectile reliability. Some parametric studies have also been included to obtain some results of field interest. (C) 2002 Elsevier Science Ltd. All rights reserved.
