Ammonium picrate (AP) is used only where a high explosive is required that is particularly iasensitive to shock. It has been employed ia pressed form primarily as a burster ia aaval projectiles for armor peaetratioa. The compouad is very stable and does not form sensitive metallic salts. Its explosive...

Hoses must be made for anhydrous ammonia service 2500 kPa (348 psig) working pressure and stamped for this service. In locations where hoses may be abraded, wke braid armored or reinforced hose types should be used. Hose ends should have boss or other acceptable ak kon ferruled couplings. 

In consumer appHcations, titanium is used in golf club heads, jewelry, eyeglass frames, and watches. The Japanese have promoted the use of titanium in roofing and monuments. Other appHcation areas include nuclear-waste storage canisters, pacemaker castings, medical implants, high performance automotive appHcations, and ordnance armor. 

Uses. Apphcations for boron carbide relate either to its hardness or its high neutron absorptivity ( B isotope). Hot-pressed boron carbide finds use as wear parts, sandblast no22les, seals, and ceramic armor plates but in spite of its hardness, it finds Httie use as an abrasive. However, this property makes it particulady usehil for dressing grinding wheels. 

Armor. Sihcon carbide is used as a candidate in composite armor protection systems. Its high hardness, compressive strength, and elastic modulus provide superior baUistic capabihty to defeat high velocity projectile threats. In addition, its low specific density makes it suitable for apphcations where weight requirements are critical (11). 

Flame Throwers and Projectors. One advance ia flame throwers siace World War II was a mechanized flame thrower kit for a variety of armored vehicles other than the main battle tank. The multishot, lightweight, shoulder-fired, four-tube flame system capable of firing one to four flame rounds semiautomaticaHy is replacing the portable flame thrower. Indeed the mechanized flame thrower is expected to become obsolete because of the family of large-cahber flame rounds. 

Cast-iron flanges (ANSI B16.1, 125-lb bolt spacing) are permanently attached to the porcelain with high strength acid-resistant cement. Flanged chemical-porcelain 90° and 45° elbows, tees, crosses, reducers, caps, and globe valves of the Y pattern are available. Armored chemical porcelain is furnished with 1.5- to 2.4-mm- (Mfi- to...

Graphite and ceramic vessels are used fully armored that is, they are enclosed within metal pressure vessels. These materials are also used for boxlike vessels with backiug plates on the sides. The plates are drawn together by tie bolts, thus putting the material in compression so that it can withstand low pressure. 

Investigations in the field of shoek eompression of solid materials were originally performed for military purposes. Speeimens sueh as armor were subjected to either projectile impact or explosive detonation, and the severity and character of the resulting damage constituted the experimental data (see, e.g., Helie, 1840). Investigations of this type continue today, and although they certainly have their place, they are now considered more as engineering experiments than scientific research, inasmuch as they do little to illuminate the basic physics and material properties which determine the results of shock-compression events. 

Eulerian codes are often used to simulate high-velocity impact and penetration events, such as shown in Fig. 9.26. Here the problem involves the penetration of armor steel by a tungsten projectile at normal incidence.
