“…The composite will typically be made up of matrix material and some form of reinforcement. Composite materials with high strength-to-weight ratios, such as carbon fibre-reinforced polymers CFRPs or aramid fibres (e.g., Kevlar), are commonly utilised in structural armour applications [8]. Later, when used as a cover for fibre glass armour [9], glass proved useful.…”

Reinforced concrete (RC) is one of the most versatile materials used worldwide due to its strength, mouldability, excellent design life and low maintenance cost. The RC structure sustains several types of load during its service period. Unpredictable loads, such as blast loads, may come to the structure intentionally or accidentally. It is necessary to assess the behaviour of the structural element and its strengthening techniques. Structural elements may strengthen using Aramid fibre, CFRP, GFRP, etc. In the case of blast loading, armour is used as an external strengthening and gives better protection than other strengthening techniques. Armour is a protective material to protect any structural element from the sudden impact of load. Based on the composition, armours are broadly categorised as ceramic-based (Glass-ceramic), metal and alloy-based (steel) and composite ceramic (Fibre reinforced polymer with metal). Composite ceramic is lightweight and cost-effective compared with other armour materials. This study has discussed a detailed review of armour, and available experimental and numerical modelling data have been compared to evaluate its performance. It shows that numerical simulation can predict more accurately. Several types of armour damage have been observed, from which the critical parameters are maximum central deflection and plastic deformation of the armour sheet. Plastic deformation of the armour sheet increases when sheet thickness reduces. However, it performed better in bending when the thickness of the plate increased.

Armor steels are difficult to weld due to the high percentage of carbon. The coarse-grained area and the fusion line in the welded joint are sensitive areas due to the high hardness and the possible presence of hydrogen produced during the welding process. Furthermore, multi-purpose armored vehicles made of armored steel are exposed to dynamic loading due to traffic on rough terrain. High hardness in the coarse- grained area of the heat-affected zone and dynamic loading can cause cracks. In the weld metal zone, a crack created during the welding process or due to pores can quickly propagate toward the sensitive fusion line, after which its accelerated growth can occur. Based on the above, achieving a welded joint without porosity or cracks for armor steel is necessary. This paper investigated the welding process of high- hardness armor steel with two regimes. The test aims to achieve an optimal hardness level and a compromise between ballistic requirements and toughness. The test results showed that a high-quality welded joint and an optimal balance between hardness and toughness are achieved with increased heat input.
