“…It is essential to mention here that this numerical modelling was previously validated in the earlier study of Biswas and Datta, 24 considering each component of the armour system separately. In the first case, the composite material model was validated considering a monolithic Kevlar 29-epoxy target block.…”

In the present study, finite element analysis were carried out to investigate the ballistic performance of Al2O3-Kevlar 29/epoxy armour system impacted by a 4340 steel projectile. The perforation capacity of a 10 mm thick target was studied against a blunt, ogive, and conical shaped projectile with a fixed diameter and mass of 7.56 mm and 10.7 gm, respectively. The simulations were carried out in Ansys/Autodyn by considering the projectile as a deformable body. The variation of the ballistic limit velocity (BLV) and energy, progressive damage of the target, and projectile deformation were studied comprehensively. It was found that the nose configuration of the projectile significantly influence the target’s ballistic performance. The perforation capacity of the blunt projectile was lower than the ogive and conical shape in all the velocity regimes. At higher impact velocity ( Vi >600 m/s), the target’s resistance was better against the ogive projectile than that of the sharp conical projectile. Interestingly, this phenomenon got reversed when the incident velocity nears the ballistic limit. Also, from the simulation results, it has been possible to obtain the optimum thicknesses of the components for a given total thickness of the armour.

“…Flores Johnson et al 20 used the Abaqus/Explicit solver to investigate the impact response of bio-inspired nacre-like aluminium alloy-based laminated composites of different thicknesses with a rigid hemispherical projectile and a 5.4 mm thick bio-inspired nacre laminated composites target performed well. Biswas and Datta 21 conducted the numerical ballistic response of multilayer ceramic fibre composite by varying impact velocities in the range of 330–1200 m/s using Ansys/Autodyn solver. They also studied and reported the variations of projectile speed, penetration time and damage behaviour of fibre composites.…”

“…So far, the literature has dealt with a variety of numerical and experimental ballistic studies on composite materials, surface modifications, reinforcement of metal matrix composites, different kinds of projectiles and their shapes, optimized ballistic limit velocities, and friction stir process plates. [1][2][3][4][5][6][7][8][9][10][12][13][14][15][16][17][18][19][20][21][22][23][24][25] Furthermore, there are numerous reports in the literature on the high-velocity impact of various Al alloys; a comprehensive study on the projectile's penetration behaviour in single layered rolled condition plates of various thicknesses and heat treatments are needed. As a result, the specified condition of heat treatment and optimized target thickness necessary to prevent complete penetration can be chosen.…”

Optimization of target thickness and influence of heat treatment condition on the high velocity impact response of aluminium alloy 7075 targets have been determined. Both experimental and numerical studies were conducted using a 7.62 mm hard steel core projectile. The numerical simulation used a 7.62 mm Ogival nose shaped projectile with a target thickness ranging from 20 to 26 mm. High velocity impact experiments on T651 and solution treated targets, with rolled plate thicknesses ranging from 21 to 25 mm were carried out to validate the numerical findings. The microhardness of the targets was measured using Vicker's microhardness tester and fractographs were examined using a scanning electron microscope. The projectile penetrated regions were analyzed using light microscopy. A good correlation between the numerical and experimental ballistic behaviour of aluminium alloy 7075 targets was observed and an optimum target thickness of 21 and 24 mm was observed for the T651 and solution treated targets to prevent the projectile's penetration. It was also noted that, after the projectile's impact, solution treated targets had higher microhardness compared to T651 condition targets. This is due to higher work hardening of solution treated targets near the penetration channel. Even though T651 targets have a lower depth of penetration compared to solution treated targets, ‘splintering’ failure of the T651 targets is observed. In contrast, ‘petalling’ and ‘plugging’ kinds of failures were noticed on the solution treated targets. Thus, solution treatment of ballistic targets may enhance the ballistic limit of armoured vehicles.

In this investigation, simulations are conducted to assess the ballistic resistance of an armor system composed of 95% alumina–Kevlar 29/epoxy composite subjected to normal and oblique impact. The oblique angles are varied from 0° to 70° in the step of 10-degree increments, and the projectile's impact velocities range between 220 and 1200 m/s. The present simulation results are aligned with existing numerical and experimental data available in the literature, demonstrating the consistency and reliability of the approach. Special attention is provided to obtain the critical oblique angle at which the projectile's penetration mode switches from perforation to embedment or ricochet. The simulation results also include the projectile's residual velocities, ballistic limit velocities, and the armor system's performance in terms of penetration or damage for normal and oblique impact. It is established that the oblique angle of the projectile significantly alters the effectiveness of the ceramic–composite armor against ballistic impact. When dealing with oblique angles below 30° (< 30°), the reduction in the projectile's residual velocity, as the obliquity angle increases, is limited to a maximum of 15%. This implies that the target's perforation resistance exhibits less sensitivity to the applied load of the projectile in this range. However, when incident angles exceed 45° (> 45°), the ballistic limit velocity has a significant and abrupt rise due to the augmented effective target thickness under oblique impact conditions.
