Penetration into soils is often described with a Poncelet equation: 2 dV M CAV R dt =+Ο . (1) Here, M is the mass and V is the velocity of the projectile, C is essentially a drag coefficient, Ο is soil density, and R represents the soil strength . Coarse measurements using time-of-arrival
A steel sphere of radius a = 0 .6 cm is shot into sand at the impact velocity of 850 m/s and zero obliquity . The density of the sand is 1 .82 g/cm3 . The simulations use a bed size of 25 cm Γ 4 .8 cm Γ 4 .8 cm . Particle size is 0 .1 cm . The maximum penetration distance was recorded to be 18 cm .

2 .1 Journal of Soil Mechanics and Foundations, 1969 (5) Prior to the 1967 publication of the penetration equations('), the Sandia terradynamics program was classified, and there were few foirmal publications on the subject . In 1969, the basic penetration equations were published in the Journal of Soil Mechanics and Foundations(') .

Penetration Mechanics I (references are in lecture 11 notes) 1 . Rigid Penetration of Targets Projectiles may be rigid or deforming . Rigid projectiles include nails, hard bullets, and low velocity penetration of fluids and soils . Deforming projectiles include bullets hitting hard armor, warhead-launched fragments and the fragment simulating
Sensitivity of the force resisting penetration of projectile into soils to the variation of the parameters of the soft soil model was earlier analyzed computationally and experimentally in , . Fig . 3 presents the forces resisting to the penetration of a cylindrical flat-ended striker into dry sand on time at impact velocities close to 180 and . . .
