What is the Monroe effect?
Definition of Munroe effect : the greatly increased penetration of an explosive into a surface (as of metal or concrete) that is caused by shaping a conical or hemispherical hollow in the forward end of an explosive cartridge.
What is meant by shaped charge?
Definition of shaped charge : an explosive charge the energy of which is focused in one direction so that it usually achieves an armor-penetrating effect.
What is a shaped charge warhead?
Abstract: A shaped charge warhead comprises a fragmenting wall defining a space which contains a shaped charge liner that is conical in shape having a large diameter base.
What does a shaped charge look like?
A shaped charge is usually a conical shape, as shown in Fig. The explosive charge is often contained in a plastic tube whose upper part looks like a cylinder and whose lower part ends at a cone of metallic liner. The liner material may be steel, aluminum, copper, and other metallic materials. Figure 25.3.
What are shaped charges made out of?
military explosives A shaped charge normally consists of a cone made of metal or glass surrounded by a high-strength, high-density explosive and means to obtain the proper standoff,…
Who invented the shaped charge?
Henry Mohaupt
Shaped charge warheads were promoted internationally by the Swiss inventor Henry Mohaupt, who exhibited the weapon before World War II. Before 1939, Mohaupt demonstrated his invention to British and French ordnance authorities.
What is hollow charge effect?
Definition of hollow charge : an explosive which concentrates its force in one direction (as in a projectile designed to blow a hole through armor plate)
Who invented the shape charge?

How do linear shaped charges work?
How do shaped charges work? In Linear Shaped Charges, the LSC or FLSC explosive material generates a detonation high pressure wave traveling through its length. The focusing of the high-pressure wave collapses the metal sheath forming a high velocity metallic jet.
What does Hesh stand for?
High Explosive Squash Head
High Explosive Squash Head (HESH) in British terminology, or High Explosive Plastic/Plasticized (HEP) in American terminology, is a type of explosive projectile which utilizes a plastic explosive that conforms to the surface of a target before detonating to improve the transfer of explosive energy to the target.
What is the Munroe effect and what causes it?
The Munroe effect is named after Charles E. Munroe, who discovered it in 1888. As a civilian chemist working at the U.S. Naval Torpedo Station at Newport, Rhode Island, he noticed that when a block of explosive guncotton with the manufacturer’s name stamped into it was detonated next to a metal plate, the lettering was cut into the plate.
When did Munroe discover the hollow charge?
Although Munroe’s discovery of the shaped charge was widely publicized in 1900 in Popular Science Monthly, the importance of the tin can “liner” of the hollow charge remained unrecognized for another 44 years.
What are the uses of shaped charges in real life?
In non-military applications shaped charges are used in explosive demolition of buildings and structures, in particular for cutting through metal piles, columns and beams and for boring holes.
When was the first crude shaped charge made?
In 1894, Munroe constructed the first crude shaped charge: Among the experiments made was one upon a safe twenty-nine inches cube, with walls four inches and three quarters thick, made up of plates of iron and steel
