Numerical Simulation and Parametric Study of Penetration Effect for an Ogive-Nose-Shaped Projectiles Against Concrete Target

Abstract

AbstractThis paper summarizes the application of numerical simulation and empirical approach to examine the penetration effect of an ogive-nose-shaped projectile against a concrete target. Many researchers were working on a concrete target as it is pertinent in structural applications such as bunkers, buildings, dams. Furthermore, reinforcement in concrete minimizes the scabbing and spalling of the target material. Thus, the concrete target is reinforced with steel bars of different grades and is tested by impacting projectiles by varying its nose shape. Our main focus was to compute the maximum depth of penetration and crater diameter in the concrete target material. Here, various numerical simulations are carried out for an ogive-nose-shaped projectile against a plain as well as reinforced concrete target at an impact velocity of 350 m/s. The simulations are performed using a commercial hydrocode ANSYS AUTODYN, a well-known software to compute transmission of shockwaves as a utility of time, and their results are compared with empirical equations. Lagrange interaction is applied between projectile and target material. The outcomes which are acquired from the simulations express upright promise with the empirical calculations.KeywordsProjectilePlain and reinforced concrete target (PCT & RCT)Depth of penetration (DOP)Calibre radius head (CRH)Crater diameterEmpirical equation
