Abstract
In design of defence structures, concrete is often used to provide protection against incidental dynamic loadings such as the impact of a steel projectile. In the present study, a new analytical model is proposed to predict penetration depth into concrete targets by ogive nose projectile. Hence, to ¬ develop the model and simulate penetration of high velocity ogive-shape nose steel projectiles into concrete targets, several tests have been simulated numerically with the Ls-Dyna finite element code. The results show good agreement between the developed analytical model and the experimental results from other researchers.
