Numerical Simulation of Ogive-nose Projectile Penetration into Plain Concrete Targets

It is important for the design and research of the defense engineering and earth-penetrating weapon warhead to study the penetration effect of plain concrete.This paper builds 3D finite element model to simulate the ogive-nose projectile penetration into plain concrete targets.Based on Young formula and cavity expansion theory,the comparative analysis of penetration effect is conducted between the numerical simulation and the empirical formula of experiment or theory formula about penetration depth and penetration deceleration,which shows the numerical simulation is highly reliable.So the study enriches the research way and method of the penetration into plain concrete targets.
