Aiming at the damage process of cutting target plate of kinetic energy projectile, the finite element models of projectile body-target plate and blade-target plate were established by using ANSYS/LS-DYNA dynamics software, and the projectile body and blade penetrating target plate were numerically simulated. The results show that the kinetic energy projectile can effectively cut the target plate after equivalent substitution at a minimum velocity of 108km/h, and with the increase of velocity, the residual velocity of projectile body and blade after cutting the target plate also increases gradually. The residual velocity of the blade is different at different times. The earlier the blade cuts the target plate, the greater the residual velocity.
