“…This allows us to compare our numerical results with those of the literature. Figure 2 displays a comparison between our numerical results and those of Guo et al 25 It can be observed that our numerical results are in good accordance with results reported in the literature. During the impact of the body armor plate with impact velocities of 650 and 850 m/s, no penetration is observed, resulting in a residual velocity equal to 0 m/s.…”

“…For the validation of the developed numerical model, three impact velocities of 650, 850 and 950 m/s are adopted. The same geometry, material properties and boundary conditions as those used by Guo et al 25 are retained. This allows us to compare our numerical results with those of the literature.…”

Hard body Armors are often deployed in ballistic applications to enhance resistance to Armor Piercing projectiles (AP). The main challenge for body armor designers is to find a best compromise between strength and weight to ensure a given level of protection. This paper investigates the effect of layer arrangement order, ceramic layer thickness, composite backing layer thickness and impact velocity on body armor performance using a numerical experimental design. In addition, the influence of bullet diameter on target damage and bullet erosion is examined. A finite element model (FEM) is evolved through Abaqus explicit software to simulate the ballistic impact of an ogival‐nosed projectile against body armor composed of a ceramic forward layer and a composite rear layer. The results revealed that the layout of the ceramic layer on the front side, that is, directly in contact with the projectile, and the composite layer on the rear side provides better ballistic performance than the opposite case. Furthermore, it is found that the thickness of ceramic and composite plates has a considerable impact on the ballistic performance of body armor. The ceramic thickness has a greater influence on the residual velocity than the composite one. Moreover, the full penetration and nonpenetration zones of the projectile have been highlighted according to the thicknesses of the ceramic and composite layers and using two impact velocities.Highlights Development of a numerical model simulating ballistic impact Study the ceramic and composite thicknesses effect on ballistic performance.

“…When the projectile strikes a single cell directly or close to the interface with another cell, the velocity is minimal. Simulations by Guodong Guo et al [ 42 ] showed that impacts at the corners and edges of honeycomb cells produce a lower residual velocity of the projectile when impacted at 850 m s −1 . Therefore, the resistance that results when the honeycomb cell is hit in the center represents the optimal outcome for safety.…”

This study employs finite element simulation to conduct a numerical modeling of ceramic–composite structure armors. The numerical armor models consist of a ceramic plate and a composite backing plate. Alumina oxide and silicon carbide ceramic materials with two different cell structures are used: hexagonal and square cell structures, respectively. A Kevlar composite is used as the back plate. The ceramic plate's thickness is altered among 7, 8, and 9 mm to explore its influence on the ballistic performance of the armors. The damage fracture is compared with experimental results, and the ballistic resistance is further examined by determining the projectiles’ velocities at the conclusion of the simulation and the evolution of the average velocity during the impact period. The findings of the numerical modeling reveal that the ceramics sustain damage consistent with the experimental damage. However, as perforation is observed in every sample, the overall performance of the samples is deemed unsatisfactory.

“…Different matrix materials are applied for the fabrication of new composites. The most popular are polymers [ 1 , 2 , 3 , 4 , 5 , 6 ], ceramics [ 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 ], cement [ 22 , 23 ], or metal [ 24 , 25 , 26 , 27 , 28 , 29 , 30 ], which joint different kinds of reinforcements, e.g., particles, fibres, and others. The above novel multiphase materials are demanded for space and cars, industrial applications [ 16 ], etc.…”

Silicon carbide foam is a material that can be used as reinforcement of interpenetrated composites. This paper presents an analysis of such a foam subjected to low and fast compression. The analysis is performed using the peridynamics (PD) method. This approach allows for an evaluation of failure modes and such effects of microcracks nucleation, their growth, and, finally, fragmentation. Furthermore, the material appears to behave qualitatively and quantitatively differently while subjected to low- and high-speed steel piston movement. Under slow compression case, damage appears in the entire specimen, but the shape of the structure is not changing significantly, whereas during the fast compression the sample is dynamically fragmented.
