Shaped charge - Wikipedia
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 …
Explosively formed penetrator - Wikipedia
An explosively formed penetrator (EFP), also known as an explosively formed projectile, a self-forging warhead, or a self-forging fragment, is a special type of shaped charge designed to penetrate armor effectively, from a much greater standoff range than standard shaped charges, which are more limited by standoff distance. As the name suggests ...
A shaped charge is a concave metal hemisphere or cone (known as a liner) backed by a high explosive, all in a steel or aluminum casing. When the high explosive is detonated, the metal liner is compressed and squeezed forward, forming a jet whose tip may travel as fast as 10 kilometers per second. Shaped charges were first developed after World ...
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
Shaped Charge - an overview | ScienceDirect Topics
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).
Basically scaling of a shaped charge depends on the use of the appropriate materials, geometry, and spacing which will result in optimum values for jet length and density to match the target requirements.
What is a Shaped Charge? (with pictures) - AllTheScience
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 …
A cylinder of explosive with a hollow cavity in one end and a detonator at the opposite end is known as a hollow charge.
Shaped charge | explosive | Britannica
The shaped charge was an explosive formed into a hollow cone and lined with heavy metal; upon detonation, the explosive gases and molten metal formed a high-velocity jet capable of punching through armour.
The cavity formed becomes deeper when the explosive charge containing the liner is removed some distance away from the plate. This distance, for which an optimum exists (Figure 3), is called the standoff distance. Devices of this nature are …
