Numerical Simulation of Penetration for Tungsten-Alloy Projectile Penetrating Cylindrical Shell Target

The process of penetrating anti-ship missile warhead shell target with tungsten-alloy projectile of anti-missile naval gun system was numerically simulated by the finite element code ANSYS/LS-DYNA.The remaining velocity and kinetic energy of the tungsten-alloy projectile were obtained respectively with the different speeds and different penetrating locations,and compared with the results of the flat target penetrating with the same projectile.The simulation results show that the location of penetrating has effects on the remaining velocity and kinetic energy of the projectile,and the process of cylindrical shell target penetrating by the same projectile is similar to the flat target.
