“…The FSC task is to activate the reactive armor before the arrival of the follow-through-warhead so it can penetrate the main armor. In a study, Harikrishnan and Murthy (2010) investigated the inconsistent performance of these shaped charges in different situations. Their investigations showed that remained part of the FSC asymmetrically enters the jet formation space of the Follow-Through-Warhead, and disturbs the formation process of the jet.…”

Shaped charges are devices used for cutting or penetrating different aerial, on land, and underwater targets, based on the concentration of the explosion energy to the liner. The purpose of this study is to present a practical review of the studies related to shaped charges in the last twenty years (2000–2020). In this regard, these studies have been reviewed in two different categories for ordinary and advanced shaped charges. In the case of ordinary shaped charges, different aspects including shaped charges against different targets, different types of shaped charges (such as linear shaped charge and explosively formed penetrators), and theoretical advancements are presented. On the other hand, the new kinds of shaped charges developed for a specific purpose are introduced in the case of advanced shaped charges. The survey of the literature indicates that different concepts such as cut-off velocity and theoretical applicability of hydrodynamics theory in shaped charge penetration still Requires effort. Also, few studies have been focused on new shaped charges, such as hyper-velocity shaped charges, annular and dual-mode ones; and the field is still open for further progress. Besides, some of these new shaped-charges, such as double-layer shaped charges, are not realistic enough to be produced for practical purposes or the market.

“…Changing the liner material of FSC, Harikrishnan and Murthy (2010) tried to improve the performance of the tandem shaped charges. They showed that the application of low-density materials, such as Lucite and Plexiglass in FSC liner resulted in lower destruction of the followthrough-warhead against ERA.…”

“…To increase the penetration performance of warhead, some different kinds of tandem warhead structures were proposed, whose penetration performance was better than that of traditional kinetic energy warhead [1][2][3][4]. The damage microstructure especially adiabatic shear band of different metal plates, such as the steel and tungsten alloy plate impacted by projectiles were investigated by ballistic experiment [5][6][7].…”

In order to study the penetration performance of the tandem warhead composed of a front circular shaped charge and a rear penetration projectile, a grooved steel plate was processed to simulate the effect of circular shaped jets on metal plate, then the failure mechanism of the grooved steel plate impacted by rear projectile was investigated by ballistic experiment, meanwhile, the effect of projectile nose shape on the failure mechanism was also analyzed. The results show that the main failure mechanism of grooved steel plate is ductile tensile deformation or damage when the projectile impacted on the inner plate body and the depth of the pre-splitting groove is not big enough (usually more than 4mm), on the other hand, the circumferential sheared fracture of the bottom of the groove occurred when the depth of the pre-splitting groove is not less than 4mm. The oval projectile body has much greater erosion damage than rod-shaped projectile during the penetration process.
