Underwater explosion load can be divided into impact load and bubble action load, which
can cause local or global damage to ship or submarine. The explosion-proof design of ship …

The dynamic failure process of structures under extreme loadings is very common in many
fields of engineering and science. The smoothed particle hydrodynamics (SPH) method …

Reinforced concrete (RC) columns are widely used as supporting structures for high-piled
wharfs. The study of damage model of a RC column due to underwater explosion is a critical …

Reinforced concrete (RC) structures are common in engineering, and usually exposed to air
or water, may be subjected to various blast scenarios. This paper aims to investigate the …

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 …

The shape of a high-explosive is an important factor to consider in the near-field and contact
explosion, but this has been rarely studied previously. In this paper, we first conduct …

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 …

Recently, external terrorist activities have become one of the most influential events on
structural safety because of the absence of proper mechanisms to detect these events. In …

The classical shaped charges are well known for their capability to yield a small ratio of the
hole diameter to charge diameter in metallic targets. However, in specific situations, for …

Limited studies available are presented to investigate the shape and orientation effect of
pressure distribution and peak pressure of non-spherical charge in near-field underwater …
