“…However, before implementing the ballistic test, the armor structure must be clamped using the backing material fixture. This equipment comprises several parts, such as a square frame, rigid plates, a hollow shaft, and the ground base [18]. The backing material fixture is constructed from a square frame.…”

The hybrid composite sandwich was carefully assembled with silicon adhesive bonding the core and skins.• The composite skins were fabricated using the hand lamination technique. • Authentic ballistics tests were conducted on the fabricated specimens. • The refined design, sample (S3), effectively protected against penetration. • Silicone rubber fillings have higher energy absorption compared with foam fillings.Hybrid composite sandwich structures, known for remarkable energy absorption, rigidity, and strength, are emerging as a preferred choice for fortifying structures against a diverse range of firearms and artillery. Despite their higher density, these panels demonstrate commendable qualities, making them optimal for armored vehicles and body armor. Numerous structural options compete for recognition as effective ballistic shields in today's context. In this study, three sample configurations were rigorously tested for ballistic impact using a 7.62×39 mm bullet. The first sample (S1) comprised silicon carbide ceramic tiles (SiC), Kevlar fiber, and carbon fiber in the face sheet, with an unfilled aluminum honeycomb core and a carbon fiber rear sheet. Subsequent samples, S2 and S3, maintained the S1 composition but varied in the core. S2 had a honeycomb core injected with polyurethane foam, while S3 utilized a silicone rubber-filled honeycomb core. Ballistic tests revealed a notable difference: S1 and S2 failed to prevent bullet penetration, whereas S3 successfully met this crucial objective. After penetration, the bullets' velocities were S1 -45.9 m/s, S2-22.9 m/s, and S3 -0m/s. Remarkably, S3 exhibited an optimal 0mm back face signature (BFS) and a penetration depth (DOP) of 13.74 mm, well within limits. Cumulative energy absorption (EA) was as follows:

“…A summary of seminal experimental impact results and discussions of basic penetration mechanisms is given in [1,2]. These studies characterize a number of plate impact perforation mechanisms as (1) fracture due to stress waves [3][4][5][6][7], (2) radial fracture behind a stress wave [5,[8][9][10][11], (3) spallation [9,[12][13][14][15][16][17], (4) shear plugging [13,[18][19][20][21][22][23][24][25], (5) petaling [19,[26][27][28][29][30][31][32], (6) fragmentation [9,[33][34][35][36][37][38], and (7) ductile-hole enlargement [39][40][41]…”

An internal state variable (ISV)-based constitutive model has been used within a Lagrangian finite element analysis (FEA) framework to simulate ballistic impact of monolithic rolled homogenous armor (RHA) steel plates by RHA steel spheres and cylinders. The ISV model predictions demonstrate good agreement with experimental impact data for spherical projectiles. A simulation-based parametric sensitivity study was performed to determine the influence of a variety of microstructural and mechanical properties on ballistic performance. The sensitivity analysis shows that the lattice hydrogen concentration, material hardness, and initial void volume fraction are dominant factors influencing ballistic performance. Finite element simulations show that variation of microstructure properties could explain the reduced ballistic performance of high hardness materials previously documented in the literature. The FEA framework presented in this work can be used to determine material properties conducive to ballistic-impact resistance.
