The Behaviour of Metals Under Ballistic Impact at Sub-Ordnance Velocities

  • Chapter
Material Behavior Under High Stress and Ultrahigh Loading Rates

Part of the book series: Sagamore Army Materials Research Conference Proceedings ((SAMC,volume 29))

Abstract

The behaviour of a material when struck by a projectile depends strongly on the velocity of impact. A useful method of characterizing the damage regime is by means of a dimensionless “damage number” (1), D:

$${\text{D}} = \rho _{\text{T}}{\text{v}}^2 /{\text{Y}}_{\text{T}}$$
(1)

Here ρT is the density of the target material and YT is its flow stress: v is the impact velocity.
