“…Figure 13 compares the current study with the previous experimental studies and indicates the difference in % age DOP for the present research and previous studies with the increasing thickness of laminated armour. In the figure, the pattern observed was nearly similar to previous experimental studies [31,32].…”

“…It had been shown that only ALON and sapphire had the required strength to act as a hard front-faced layer in laminated glass, but the current study improvises it to a Silicon carbide hard front-faced layer also. Shutov et al [32] had done experimental testing of the laminated glass of varying thickness, with a Makarov pistol. In figure 13, only the results of a shooting distance of 10 m have been compared.…”

Currently, silicon carbide (SiC) is of enormous concern because of its high compressive strength, high thermal conductivity, high thermal shock resistance and small coefficient of thermal expansion. SiC has its applicability in armored vehicles, hypersonic armaments, and bullet-resistant armours in the future. The current focus is on understanding the behavior of SiC as used in laminated ceramic armours during the ballistic impact for its profound use in armoured vehicles. To achieve these objectives, computational simulations have been performed for the aforementioned materials using ANSYS/AUTODYN. It was concluded that when SiC was used as a front layer in laminated armours, it significantly increased the strength of the material against the hitting projectiles. The aforementioned composite material was even successful against the sniper gun projectile. The optimized thickness for the given configuration was found to be 41 mm with the consideration of approximately 50% depth of penetration. The modeled configuration was found to be approximately nine times stronger than the conventional laminated armours. The current study was compared with the previous experimental studies and the results were in good agreement. This agreement solely pertains to the pattern observed and not to individual values. It indicated the difference in % age DOP for the present research and previous studies with the increasing thickness of laminated armour. The trend observed was nearly similar to previous experimental studies. This showed that the DOP was reduced, as the thickness increased. Moreover, the previous studies showed that only ALON (aluminium-oxynitride) and sapphire had the required strength to act as a hard front-faced layer in laminated glass, but the current study improvised it to a Silicon carbide hard front-faced layer also.

“…However, when the average of DOP data from three samples of each sort from the experimental testing was taken, the over-prediction does not appear to be significant. In comparison to earlier research [31,35], the trend seen in the figure was virtually identical. That is, as the thickness increases, the DOP drops.…”

The Drucker Prager material model, Ductile Damage and Mie-Gruneisen equation of state parameters for high-pressure densification induced glass were derived analytically in the current study by comparing them to the Johnson Holmquist-II (JH-2) model. These parameters were then utilized to simulate the ballistic impact behaviour of bullet-resistant glass in ABAQUS/Explicit and the results were compared to the simulation results using JH-2 model in ANSYS/Autodyn and the results were found in good agreement. Following that, their experimental equivalents were tested for validation prospective. The findings were then compared to conventional bullet-resistant glass. It was found that the new bullet-resistant glass fabricated from layers of high-pressure densification induced glass was superior in strength as compared to the conventional bullet-resistant glass.
