A new type of annular shaped charge was utilized to enhance penetration performance into
underwater structures in this paper. Explosive Formed Projectile (EFP) which can be formed …

This study aims to investigate the formation characteristics and penetration performance of
an underwater conical shaped charge jet. First, a new theoretical model for underwater jet …

In this paper, the authors presented an analysis of the strengthening of the cumulative jet by
the appropriate formation of the detonation wave front acting under the influence of high …

High-speed metal jets induced by shaped-charge warheads in underwater weapons may
initially damage the bottom of a ship. Subsequently, the load from a subsequent underwater …

With the improvement of the antiknock performance of warships, shaped charge warheads
have been focused on and widely used to design underwater weapons. In order to cause …

The shaped charge jet (SCJ) is a devised physical phenomenon that involves high-speed
collision of material particles, fluid–structure interaction, dynamic fracture, and complex large …

Jet formation was studied by performing theoretical analyses and numerical calculations,
and a predictive model was proposed. X-ray experiments were conducted to verify the …

This paper presents a new approach to model phase transitions in multi-material problems
based on the assumption of thermal equilibrium. The method is used to construct an …

To further enhance the hole-opening ability of the metal jet formed by the annular shaped
charge on the armored steel target, a new annular shaped charge structure of a closed-cell …

In order to analyze the influence of a water medium on the forming process and penetration
performance of a shaped charge jet, a comparative study was carried out on an underwater …
