The word is sometimes used to refer to an individual diamond in the design, but more commonly refers to the overall pattern. Most argyle contains layers of overlapping motifs, adding a sense of three-dimensionality, movement, and texture. Typically, there is an overlay of intercrossing diagonal lines on solid diamonds.
Advanced Modular Armor Protection (AMAP) is modular composite armour concept, developed by the German company IBD Deisenroth Engineering, since 2019 part of Rheinmetall Protection Systems. According to IBD AMAP is a 4th generation composite armour, making use of nano-ceramics and modern steel alloy technologies. [ 1 ]
Phaneritic rock: Anorthosite from the Stillwater Igneous Complex (Neoarchean; Montana) Igneous textures include the rock textures occurring in igneous rocks.Igneous textures are used by geologists in determining the mode of origin of igneous rocks and are used in rock classification.
A Chinese publication lists 30MnCrNiMo "685" steel as the material used in Chinese rolled armor plates, with a Brinell Hardness of HBW 444-514 (thin) / 429-495 (thick). According to the same publication, older vehicles use a 22SiMn2TiB "616" steel with a hardness of HBS ≤ 219.
The air-space between the belt and the hull also adds buoyancy. Several wartime vessels had belt armour that was thinner or shallower than was desirable, to speed production and conserve resources. Deck armour on aircraft carriers is usually at the flight deck level, but on some early carriers was at the hangar deck. (See armoured flight deck.)
Issued to infantry, the user would run up to the tank and place the device on any surface to which the magnets would stick. The user would then pull the safety pin and run for safety. The magnets not only held the mine to the vehicle but also provided the correct spacing between warhead and armor, allowing the penetrator jet to form properly.
This is the initial stage of K-metasomatism in cataclastically-deformed magmatic plutonic rocks. The breakage happens primarily along grain boundary seals and the K-metasomatism may locally replace rims of zoned plagioclase crystals to form interstitial alkali feldspar and rim myrmekite (see illustration).
A left-arm vambrace; the bend would be placed at the knight's elbow An ornate German (16th century) vambrace made for Costume Armor. Vambraces (French: avant-bras, sometimes known as lower cannons in the Middle Ages) or forearm guards are tubular or gutter defences for the forearm worn as part of a suit of plate armour that were often connected to gauntlets.
