Armor steel

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. 

Pellets, slugs or flechettes made of U have very good powers of penetration. However, U is softer than steel so that in the process of penetrating an armored steel plate it is partially pulverized. Since in this form U is pyrophoric (self-igniting), such projectiles have an incendiary as well as a penetrating effect. According to one account of flechettes made of depleted U ... 

The usual precautions regarding temperature and vibration control also apply to the ultracentrifuge. To overcome air resistance and the attendant frictional heating, the compartment in which the rotor spins is evacuated and may be thermostated over a wide range of temperatures. The rotor is mounted on a flexible drive shaft that minimizes the need for precise balancing as a requirement for vibration-free operation. Finally, the rotor assembly is enclosed in an armored steel chamber for safety. At these speeds, a runaway rotor is deadly ...

A. Kits One source for armor kits is Danegeld Inc. Box 54673, Atlanta GA 30308. Send them 1 for complete info. Danegeld sells Kevlar yardage, kits with patterns and instructions for several styles of armor, and ready made T-Shirt armor similar to the design shown in section II. They also sell the armor steel inserts mentioned in section V. 

The DAVINCH is a double-walled steel chamber. The replaceable inner vessel is made of armor steel and the outer vessel is made of multilayered carbon steel plates with a corrosion- and stress-crack-resistant inner plate made of, for example, stainless steel, Hastalloy, or a similar material. The chambers are separated by air. Owing to its double-wall design and the materials of construction, the DAVINCH has the ability to confine high-pressure detonation gases, eliminating the need for an expansion tank to contain them following a detonation. 

We have virtually eliminated damage to steel targets, Powers says. That decreases the costs of operating a shooting range. Shoot houses can now be constructed from steel plate, as opposed to the expensive, heavy armored steel/rubber anti-ricochet panel/plywood construction, which is common in the industry. ...
