“…Therefore, the targets could be considered to act as a discontinuous system as no bond is present between the two metal layers. However, if the metals could be bonded together as done through explosive welding by Zhou et al (2013) and Wang and Zhou (2015), the influence of the composite behaviour on the ballistic behaviour could be studied. Thus, such systems could be considered as continuous systems.…”

“…The authors indicated that when the incident angle of impact increases, the ballistic limit velocity increases accordingly. Wang and Zhou (2015) reported an identical set of results for the experiment conducted to find the ballistic performance of steel-aluminium explosively welded targets. A plate arrangement similar to Zhou et al (2013) was used, and the plates were impacted using 8-mm-diameter spherical projectiles with an initial velocity of 700 m/s.…”

“…The layers could be made of different metals and metallic alloys. However, steel and aluminium have been used in experiments conducted hitherto (Babaei et al, 2016;Wang and Zhou, 2015;Zhou et al, 2012). All the experimental investigations mentioned below conclude that a superior ballistic performance could be obtained when using a system of three layers where steel acts as the anterior and posterior plates while aluminium is used in the middle.…”

“…Hence, the targets act as discontinuous systems with no bond in between the metal layers. Zhou et al (2013) and Wang and Zhou (2015) conducted numerical simulations for explosively welded double-layered targets to validate the experimental results. LS-DYNA was used for simulations in both the studies.…”

“…Yet, the overall thickness can be further reduced in order to provide better performance. Zhou et al (2012) and Wang and Zhou (2015) conducted numerical investigations on continuous explosively welded triple-layered targets using nonlinear finite-element code LS-DYNA. The TIED_BREAK_SURFACE_TO_SURFACE contact algorithm was used to define the contact between metal plates.…”

Ballistic resistance enhancement of armours and structures has been a prominent area of research over the years. Monolithic metallic plates have been the preferred choice for armours against high-velocity projectiles. High-strength steel is a popular choice for such systems. However, the high areal density deters in accommodating such systems in practical applications which require lightweight products. On the contrary, multi-metallic systems produced by the combination of low-density materials with similar or superior ballistic resistance as their monolithic counterparts have become attractive candidates in defence applications. However, only a limited number of comprehensive studies on the ballistic performance of multi-metal multi-layered targets are available in the literature. Moreover, these studies have drawn contradictory conclusions on the optimum arrangement of different layers and materials within the systems. In addition, existing knowledge in this area is scattered in the literature and there is a need to collate them to enhance the development of multi-metal multi-layered ballistic-resistant plate systems in order to be optimised for ballistic-related armour. This article aims to provide a comprehensive review of the effect of different metals, thickness, fracture mechanisms, feasibility of the connection types and the order of the metallic plates within targets on the ballistic performance.
