Penetration mechanics equation


Fragmenting bullets are usually constructed like the hollowpoint projectiles described above, but with deeper and larger cavities. Cookies We use cookies to improve your experience with our site.

Common rifling twist rates also often have to be tightened to stabilize very long projectiles. Other bullets in use by militaries are quite back heavy, due to a long, sharp point created in an attempt to get the maximum ballistic coefficient see external ballistics. Such commercially nonexistent cartridges are termed "wildcats". In contrast to a hollowpoint which attempts to stay in one large piece retaining as much weight as possible whilst presenting the most surface area to the target, a fragmenting bullet is intended to break up into many small pieces almost instantly.

Ballistic Materials and Penetration Mechanics - 1st Edition

Targets of finite thickness IV. It proceeds with a discussion of variations in ballistic test methods, errors in test methods, and the importance of the hardness and geometry of both the target and the projectile. Polar coordinate system section: Euler also worked out analogous laws of motion to those of Newton, see Euler's laws of motion. The point of concurrency of the three axes is known as the origin of the particular space.

Description: In the following rotational definitions, the angle can be any angle about the specified axis of rotation. Ballistic goggle and visor materials V. The book discusses historical and practical considerations of ballistic protection, including metallic armor, as well as ballistic testing methodology, the ability of a protective material to stop or slow down a particular projectile, and the theoretical aspects of penetration mechanics. Ballistic Materials and Penetration Mechanics deals with ballistically protective materials and penetration mechanics.
