Numerical Simulation Of A New Kinetic Energy Projectile Penetration Of Reinforced Concrete

Reinforced concrete because of its excellent performance, widely used in buildingstructures, in order to prevent wartime received a serious blow, many countries and regions inthe world of high value targets and strategic targets are underground or semi-underground,various forms of concrete or reinforced concrete structure become one of the main means ofprotection goals. Research on the reinforced concrete penetration projectile penetration ofvarious protective class goal of both the important military application background, there arealso many non-military application value, therefore has important practical significance.This paper introduces about the kinetic warheads development present situation and theresearch status of penetration problem, the characteristics of reinforced concrete andreinforced concrete constitutive model are briefly introduced. On this basis, a new type ofkinetic energy projectile penetrating reinforced concrete plate is simulated by LS-DYNA.Projectile penetration of different parameters to invade the target board of numericalsimulation, obtained different head sizes projectiles with different Angle of the target speed,the penetration of penetration of reinforced concrete plates after deposit speed curve as wellas the internal energy of explosive, shock acceleration curve, and the calculation results areanalyzed and compared, useful conclusion is obtained.With different parameters of the target plate by a numerical simulation of the penetrationis obtained under the condition of different steel thickness, the impact of the projectilepenetration after deposit speed curve as well as the internal energy of explosive, shockacceleration curve, and the calculation results are analyzed and compared, provides referencefor kinetic energy penetration warhead research.
