Numerical Simulation of Explosively Formed Projectile Penetration the Target

Explosive-formed projectile shaping and target penetration process are studied with the way of numerical simulation based on LS-DYNA.It is described that the numerical simulation model is established and by using the technique of numerical simulation,explosive-formed projectile shaping is realized and the effects of different charge structure on explosive-formed projectile shaping are analyzed,the status of warhead distortion and target destruction in penetrating process can be seen.At the same time,the simulation results are analyzed.The numerical simulation of penetrating target by explosive-formed projectile lays a good foundation for research on explosive-formed projectile destroying mechanism.
