ملخص المقالة :
In design of defense structures, concrete are 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 has been simulated numerically with the Ls-Dyna finite element code. The results show good agreement with the analytical analyses and experimental results from other researchers.
