Spin effect of the small diameter shaped charge results in the centrifugal stress during the jet stretching process. Consequently, the jet scatters, which deceases the jet penetration capability. In the present study, a multi-section method was propo

The microstructure evolution and plastic deformation mechanism of a Ta-2.5W liner under the ultra-high-strain-rate conditions generated by the explosive detonation were investigated in this study. For this purpose, a modular soft-recovery apparatus w

An analysis of the penetration–explosion (PE) effects of four distributions of inactive/active composite jets shows that a well-designed inactive/active double-layer liner can promote composite jet damage. Penetration experiments were then carried

The prediction of the fragment velocity distribution of a cylindrical cased charge with end caps is one of the key issues to assess the damage efficiency of the warhead. However, limited work has been conducted to predict the fragment velocity distri

To attach against clustered low-protection UAVs, this paper proposes a new type of whirling fragment structure and warhead arrangement. The non-linear dynamics software Autodyn was used to carry out a numerical simulation. The detonation drive of whi

In order to compare the forming and penetration process of linear shaped charge jet in three different mediums ( in the air/ under water/ under water with air standoff), threedimensional numerical simulation models were established using ANSYS / LS-D

Projectiles made of reactive structure materials (RSM) can damage the target with not only kinetic but also chemical energy, but the enhanced damage potential of RSM may become compromised if extreme loading condition disintegrates the projectile bef

The behind-armor debris (BAD) formed by the perforation of an EFP is the main damage factor for the secondary destruction to the behind-armor components. Aiming at investigating the BAD caused by EFP, flash X-ray radiography combined with an experime
