“…The anti-jet penetration performance of composite structures and materials has been the focus of researchers recently. Jia et al [2] prepared an experimental study on the anti-jet penetration performance of four types of fabric-reinforced rubber composite target plates, such as Kevlar-49 and PBO, the function of fabric fiber in the process of anti-jet penetration were analyzed. Zu et al [3] conducted an experimental research on the anti-penetration protection efficiency of rubber composite target plates and proved the anti-jet penetration performance of rubber composite armor.…”

For improving the protective performance of Armor, a multi-layer metal-diesel closed structure (MLMDCS) was proposed. The concept of equivalent layer number n and specific residual head velocity (SRHV) for describing the anti-jet penetration performance of single-layer metal-diesel closed structure (SLMDCS) and MLMDCS was put forward. The finite element simulation method by experimental verification was used to simulate the shaped charge jet (SCJ) penetrates the MLMDCS and SLMDCS. The simulation results show that when the equivalent layer number n (n>1) is the same, the residual head velocity of the jet through the MLMDCS is lower than that of the SLMDCS, and the time is longer than that of the SLMDCS. The energy consumption of jet in MLMDCS is more than that of in SLMDCS. The jet head becomes blunt after penetrating out the MLMDCS, but the head shape remains basically unchanged after the jet penetrates out the SLMDCS. The velocity streamline of diesel at the intersection of each layer in the MLMDCS is disordered, which forms local turbulence and disjoint phenomenon. The distribution positions of the diesel velocity streamline and pressure in the SLMDCS are basically the same. Compared with the SLMDCS, the MLMDCS has better anti-jet penetration properties, and the anti-jet penetration properties of the MLMDCS are better with the increase in the equivalent layer number. The research results provide a design reference for the new generation protective armor.

Passive protective armor is reliable and cheap, and is favored by many armored weapons and equipment. However, reports on metal-liquid composite armor are not sufficient and systematic. Based on the shaped charge jet (SCJ), the anti-penetration capabilities of water filled aluminum alloy cell structure were studied. The hourglass cell structure (HCS) was designed according to the shock wave propagation characteristics in liquid, and the expansion-convergence cell structure (E-CCS) was derived. Based on the virtual origin theory, the residual tip velocity of jet after SCJ penetrated the cell structure was calculated. According to the theory of supersonic disturbance propagation, the Mach cone half angle of SCJ shock wave propagation in liquid was defined and corrected. The propagation and reflection behavior of shock wave were discussed to analysis the radial convergence of liquid. Via the Van Leer Arbitrary Lagrangian Euler finite element simulation model verified by experiments, the simulation studies of SCJ penetrated the circular cell structure (CCS), HCS, E-CCS and convergence/expansion multi-cell structure were performed. The results show that HCS has better effect of interfering with SCJ than that of CCS and E-CCS. An important discovery is that when the liquid composite multi-cell structure is penetrated by SCJ, the attacked cell will not affect other cells due to the shock wave has been trapped in a single cell.

“…The effective penetration resistance and impact energy absorption of high strength woven fabrics makes them desirable in applications such as protective clothing and sport equipment, lining for luggage container, involving impact resistance [1,2]. With the development of computation technology, numerical models using finite element analyses are largely used for ballistic impact onto woven fabrics which modeled using single-scale method [3].…”

In this paper, Finite element modeling of the impact of the Kevlar woven fabric using hybrid element analysis (HEA) method has been carried out to find out a suitable ratio between area of solid elements used at impact region and area of shell elements used away from impact region. Three HEA models: about one time, two times and three times of the projectile’s diameter with 200 m/s impact velocities are constructed. The solid and shell elements with variable nodal thickness are joined together using tied interfaces in order to ensure that there are no artificial reflections of the longitudinal wave at the interface. The effect of the different ratio of local area and global area on the ballistic performance of the fabric is discussed.
