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 …

Abstract Taking the'6· 13′ major gas explosion accident in Shiyan, Hubei Province, China
as an example, three problems were studied in this work:(1) The determination of the …

Shaped charge warhead which is widely utilized for underwater weapons has a severe
threat to the survivability of naval ships. Therefore, it is of great significance to improve their …

Shaped charge liner (SCL) has been extensively applied in oil recovery and defense
industries. Achieving superior penetration capability through optimizing SCL structures …

A method based on the combination of finite element and discrete element theories is
proposed to reveal the dust raising law of gas explosion shockwaves in 3D reconstructed …

This paper examines the response characteristics of a warship's double-layer plates under a
secondary near-field explosion after the ship's outer plate has been perforated by shaped …

Featured Application (1) A gas explosion simulation combining the chemical reaction
mechanism and tunnel structure is described;(2) the shock wave flow fields in tunnels with …

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 …

The underwater explosion (UNDEX) of a shaped charge is a continuous physical process.
However, the interaction between the shockwave, the shaped charge projectile, and the …

Shaped charge has been widely used for penetrating concrete. However, due to the obvious
difference between the propagation of shock waves and explosion products in water and air …
