“…Fig 14. The proportion of plastic deformation energy absorption of plates to the overall energy absorption It is worth noting that the target plate's overall plastic deformation energy absorption of the lowest for the plane plate, while the plane plate in the lowest energy absorption for the doublelayered AA1100 target plate, about 87.396J, but its plastic absorption of energy accounted for the proportion of the overall absorption of energy is very high, reached 81.15%.…”

Scholars have studied the impact resistance of flat plates quite well. However, in practical applications, the connecting part of the protective end often presents other shapes, and the importance of this part for the protective effect should not be neglected. Therefore, it is valuable to conduct further research on the shape of target plates. This study aims to investigate the impact resistance of combined target plates of 1100 and 7075 aluminum alloys with different shapes. In this study, the failure modes of double-layered aluminum alloy plates under the impact of blunt projectiles were analyzed by changing the order of plate arrangement and the shape of projectiles, and the ballistic limits and energy absorption characteristics were determined. In addition, a 3D finite element model was established using ABAQUS/Explicit software, and after verifying its accuracy, the model of flat nosed projectile impacting other shapes of double-layered target plates was extended using the finite element method. The results show that for plane plates, arched plates and L-square plates, the sequential arrangement of ductile high metal in the front plate and strong high metal in the back plate possesses better ballistic resistance. However, for hemispherical shells, the same arrangement results in weaker impact resistance. Finally, the paper concludes that the shape of the protective ends affects the order of arrangement for optimum impact resistance.

The penetration of reactive projectile into target is an extremely complex thermomechanical coupling process, and most of the researches reveal this coupling mechanism by means of experiments. In this paper, based on the finite element simulation software ANSYS/LS-DYNA, using IGNITION_ANG_GROWTH state equation and Null constitutive model, the process of reactive projectile penetrating target is numerically modeled, and the numerical simulation model is verified by ballistic impact test. The test results are in good agreement with the simulation results. Further, according to this numerical simulation model, the ballistic limit of reactive projectile penetrating target is studied. The results show that the IGNITION_ANG_GROWTH state equation and Null Constitutive model can be used to calculate the mechanical and chemical coupling responses of the reactive projectile in the process of penetration plate effectively based on the SPH algorithm. This provides a new method to study the reactive projectile penetration-explosion coupling process.

“…This material is hence significantly lighter in weight than metals like steel due to its low density. Further the corrosion resistance of AA7075 helps maintain its structural integrity through time even in harsh combat environments [21][22][23][24][25] . In addition to that, AA7075 can easily be fabricated into any desired shape allowing it to be used in a variety of ways for ballistic protection.…”

The materials used for ballistic applications have always taken a special spot in the manufacturing and study of protective amours. Although metals like steel provide adequate ballistic protection, they compromise the mobility of the soldier and since high mobility is a primary requirement for soldiers during combat. Therefore, at present most of the researchers are currently focusing on materials with properties like high impact resistance and high strength to weight ratio. In recent times, Aluminum alloys are recognized as the alternative materials which can provide good impact resistance and have a high strength to weight ratio and having better corrosion resistant properties which ultimately make it a suitable material for several military applications. In this research, one of the toughest aluminum alloys AA7075-T6 is considered for designing an armor plate and studied for its ballistic resistance. Initially, the monolithic AA7075-T6 alloy of 18 mm was tested for its ballistic resistance limit and further it is designed with the ceramic plate of 3 mm and base alloy AA7075-T6 of 15 mm was tested to evaluate. Later the monolithic alloy of 18 mm was surface reinforced up to a thickness of 3 mm with different types of reinforcements and evaluated the bullet residual velocity after penetration of the armor piercing projectile. Numerical simulation was conducted using the prominent non-linear dynamic analysis software i.e., Ansys AUTODYNE version 19.2 and the respective values for the surface reinforced metal matrix composites revealed excellent results for the depth of penetration and residual velocity of the projectile.
