Design of an Impact Test for Estimating the Deformation Energies of Projectiles in Wound Ballistics Studies (original) (raw)

1980, Defence Science Journal

Abstract

The paper suggests an impact test which can be used to evaluate the deformation energies of small arm projectiles. * Such an evaluation is of significance in wound ballistics studies while determining the amount of energv actually consumed in causing cavitation. Various sources of error inherent in the test have been discussed and it has been concluded that although approximate, the test can serve the usefill purpose of providing a basis for interpreting the energy loss figures in gel on a rational and scientific basis.

Key takeaways

AI

1. The proposed impact test approximates deformation energies of small arm projectiles for wound ballistics studies.
2. Deformation energies calculated for the 0.315 SN bullet and 0.410 lead ball are 195 and 35 Joules respectively.
3. Energy losses in gel for the same bullets are 1770 and 976 Joules, adjusted to 1575 and 941 Joules after deformation energy deduction.
4. Various errors in the test include projectile tumbling, kinetic energy loss, and simulation accuracy.
5. The impact test serves as a practical, albeit approximate, method for interpreting projectile energy loss in gel.
