A shaped charge is an explosive charge shaped to focus the effect of the explosive's energy. Different types of shaped charges are used for various purposes such as cutting and forming metal, initiating nuclear weapons, penetrating armor, or …
Shaped charges are devices in which an explosive load is used to collapse a (usually metal) liner, thereby creating a high velocity jet that is capable of penetrating deep into metal, concrete or other target materials (Walters & Zukas, 1989).
The increase in penetration resulting from the lined shaped charge is due to the jetting process which occurs when the liner undergoes explosive-induced high-pressure, high-velocity collapse.
The collapse, formation, growth, and penetration of a jet from a shaped charge liner results in extremely high strains (>10), strain rates (10 7 /s), hydrostatic pressures (up to 200 GPa), and surface temperatures (500-600 C).
This brief overview of the development of shaped charges begins with a definition of a shaped charge. In the opinion of the author, a shaped charge is defined as a cylinder of explosive with a hollow cavity at the end opposite the initiation train. If the cavity does not contain a liner, it is referred to as a hollow
May 21, 2024 · A shaped charge is a specially-forged explosive designed to project a superheated jet of liquid metal through armor. Dense and ductile metals are most effective, with copper being the most common. Modern shaped charges …
Oct 1, 2007 · This phenomenon is what causes shaped charges to be ineffective at long standoff distances from the target: the jet continues to elongate until it literally breaks up, and the resulting jet segments have greatly diminished penetrative power.
Jun 12, 2017 · BRL scientists delineated the penetration mechanics of the stretching, high-velocity jet of metal that is formed by the warhead, thus making it possible to design relatively light, inexpensive...
shaped-charge jet is capable of creating deep cavities in materials such as hardened steel, rock, and fortified concrete. The penetration capability of the jet increases to a maximum and then decreases as the distance from the shaped charge to the target, known as the standoff distance, increases. The most common metal used as a shaped-charge ...
