For several millennia, bronze was the material of choice for weapons such as swords, daggers, battle axes, and spear and arrow points, as well as protective gear such as shields, helmets, greaves (metal shin guards), and other body armor.
An open single-cavity bullet mold and a closed two-cavity mold. A cast bullet is made by allowing molten metal to solidify in a mold.Most cast bullets are made of lead alloyed with tin and antimony; but zinc alloys have been used when lead is scarce, and may be used again in response to concerns about lead toxicity.
Formation of an EFP warhead. USAF Research Laboratory.. 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.
In 2003, an experiment performed by Lee showed much about the ballistic properties of liquid armor. The experiment showed the strength difference between standard Kevlar and STF-Kevlar. It was observed that the STF could do an extreme, sharp increase in viscosity, and as a result, it turned back to a flowable liquid almost as fast as it turned ...
The front plate was intended to break up an incoming shell, while the rear plate would catch any splinters and hold the armor together if the brittle front plate shattered. Compound armor was made by pouring molten steel between a red-hot wrought iron backing plate and a hardened steel front plate to weld them together. This process produced a ...
Late medieval gothic plate armour with list of elements. The slot in the helmet is called an occularium. This list identifies various pieces of body armour worn from the medieval to early modern period in the Western world, mostly plate but some mail armour, arranged by the part of body that is protected and roughly by date.
The long-rods are able to penetrate a much greater depth of armor, at some loss to BAE, multi-slugs are better at defeating light or area targets and the finned projectiles are much more accurate. The use of this warhead type is mainly restricted to lightly armored areas of main battle tanks (MBT) such as the top, belly and rear armored areas.
The shaped charge jet armor penetration effect is purely kinetic in nature; the round has no explosive or incendiary effect on the armor. Unlike standard armor-piercing rounds , a HEAT warhead's penetration performance is unaffected by the projectile's velocity, allowing them to be fired by lower-powered weapons that generate less recoil .
