The Numerical Simulation in Ballistics

Nonlinear Analysis, 2001
In this paper we examine the movement of the solid body thrown with some angle to the horizon (for example the shot mine). Such movement is described by non-linear system of equations. This system is being approximated by linear system, in segments.

Sand Penetration By High-Speed Projectiles [PDF]

, 2009
Tungsten projectiles were shot into sand at velocities between 600 and 2200 m/s. Penetration was maximum at about 775 m/s. Below that velocity, projectiles were apparently stabilized by a fin set.
