“…The input parameters related to the target are reported in Table 5 . The authors already determined the elastic modulus E , the Johnson–Cook parameters A , B and n , and the Cockcroft–Latham parameter W c either for Ramor 500 [ 35 ] or AA66061-T6 [ 41 ]. In particular two sets of these parameters were obtained for two plate thicknesses of Ramor 500: around 3 and 6.5 mm.…”

“…The other material parameters were obtained from the literature. Herein, the material model, already used in [ 41 ], is further validated by replicating the experimental tests performed by Piekutowski et al [ 45 ] were an ogive-nose steel projectile was impacted against a 26.3 mm thick AA6061-T651 plate. An axisymmetric numerical model which replicates the experiment was built.…”

In the case of protection of transportation systems, the optimization of the shield is of practical interest to reduce the weight of such components and thus increase the payload or reduce the fuel consumption. As far as metal shields are concerned, some investigations based on numerical simulations showed that a multi-layered configuration made of layers of different metals could be a promising solution to reduce the weight of the shield. However, only a few experimental studies on this subject are available. The aim of this study is therefore to discuss whether or not a monolithic shield can be substituted by a double-layered configuration manufactured from two different metals and if such a configuration can guarantee the same perforation resistance at a lower weight. In order to answer this question, the performance of a ballistic shield constituted of a layer of high-strength steel and a layer of an aluminum alloy impacted by an armor piercing projectile was investigated in experimental tests. Furthermore, an axisymmetric finite element model was developed. The effect of the strain rate hardening parameter C and the thermal softening parameter m of the Johnson–Cook constitutive model was investigated. The numerical model was used to understand the perforation process and the energy dissipation mechanism inside the target. It was found that if the high-strength steel plate is used as a front layer, the specific ballistic energy increases by 54% with respect to the monolithic high-strength steel plate. On the other hand, the specific ballistic energy decreases if the aluminum plate is used as the front layer.

“…Ceramic/metal composite armor is used widely in active weapons, such as the armor of the Ukrainian “fortress tank.” In recent years, many scholars have conducted a large number of theoretical studies and tests on ballistic ultimate velocity, projectile hole characteristics, and target plate deformation upon projectile penetration of ceramic/metal composite target plates. 1–5 Ceramics are used widely because of their excellent penetration resistance. Advanced ceramics such as fiber-toughened ceramics, transparent ceramics, and multi-phase ceramics have appeared.…”

The aim of this work was to study the anti-penetration effect of sandwich composite armor with ceramic honeycomb structures filled with aluminum alloy under the impact of high-speed projectiles. The finite element software ABAQUS was used to conduct numerical simulation research on the process of a standard 12.7-mm projectile penetrating sandwich composite armor. The armor-piercing projectile model was simplified as a rigid body. The numerical simulation models were applied to three different sandwich composite armor structures (A, B, and C), each with a total armor thickness of 25 mm. The penetration resistance of the three kinds of composite armor was studied. We obtained velocity curves for the rigid projectile penetrating the different structures. The failure forms and penetration resistance characteristics of the three composite armor structures adopted in this paper were analyzed. In addition, the velocity reduction ratio is proposed as an index to evaluate the penetration resistance performance of the armor. The simulation results revealed decreasing rates of projectile speed in the structures A, B, and C of 69.6%, 91.1%, and 100%, respectively. The third composite armor (structure C) designed here has excellent penetration resistance and can block the penetration of a high-speed (818m/s) rigid projectile. This study can provide some reference for the application of laminated armor material in anti-penetration protection structures.
