摘要
The finite element analysis software Abaqus/explicit was used to simulate the impact of flat nosed projectile on TC4 titanium alloy plates with different thickness. The relationship was studied between impact failure characteristics and thickness change of double-layer targets. The effectiveness of the simulation model was verified by comparing the impact tests and simulation results. On this basis, the penetration resistance of a TC4 double-layer target was compared with the same thickness of a monolithic target. The results show that the ballistic limit of the double-layer structure is approximately linear with the total thickness of the target plate in the range of 2-16 mm for the flat nosed projectile with 12.68 mm diameter. Due to the special phenomenon that the ballistic limit has no obvious change with the increase of the thickness for the monolithic target plate in the range of 4-10 mm, the double-layer target has obvious advantages over the monolithic target in the thickness range. The ballistic limit is 43% higher than that of the monolithic target when the total thickness is 8 mm. © 2021, Editorial Office of Journal of Vibration and Shock. All right reserved.
