Functionally graded concrete(FGC) targets composed of different kinds of ultra-high performance concrete (UHPC) were prepared. Some methods to improve the resistance of concrete materials to ultra-high speed jet were investiaged. The hypervelocity penetration resistance experiment and numerical simulation of functionally graded concrete protective engineering materials were performed. The anti-penetration performance of the functionally graded concrete targets was analyzed according to the aspects of damage distribution, bullet fragmentation degree, penetration damage and fracture pattern of the target by the jet penetration test. The simulated data by a finite element calculation model, established by a software named ANSYS/AUTODYN, were verified with the experimental results of jet penetration. The results show that the FGC targets can effectively block the penetration of hypervelocity jet and the penetration depth is 241 mm. The process of jet formation and penetration was analyzed by numerical simulation and its effectiveness was verified. The simulation error is 3.7%. In additon, the result of coupling damage of jet and hypervelocity projectile penetration was also predicted by a software named AUTODYN.
