Ordinary concrete target, ultra-high performance concrete (UHPC) target and functionally graded concrete target composed of different kinds of UHPC were prepared. The penetration and explosion experiments were performed on different types of concrete targets. The numerical simulation analysis was carried out by finite element method. The results show that in terms of the failure mode, the functionally graded concrete target has the smallest fracture depth, and the crater depth does not exceed the range of the anti-penetration layer under the coupled load of penetration and explosion. In terms of damage distribution, the concrete damage is mainly concentrated on the front surface and around the projectile channel and transmitted diagonally on the rear surface. Fiber reinforced targets maintain a good integrity. From the perspective of energy, the ability of absorbing projectile kinetic energy of high-strength coarse aggregates in anti-penetration layer is greater than that of concrete matrix. UHPC with a functionally graded structure has a superior anti-penetration and explosion ability.
