a novel study of penetration ‎into concrete targets by ogive ‎nose projectiles

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.
