Injury Characterization Due to Penetrating Projectiles

Abstract

Simulation tools using fast-running model forms for armor ballistic performance and penetrating injury response, coupled to Monte-Carlo based probabilistic methods to account for the inherently statistical nature of threat engagement with a PPE armor solution and penetrating injury dynamics are being developed. A critical element to the evolving predictive capability is development of improved model forms that account for the complex interactions between the threat, armor, and human body. These improved models require validation data from appropriate experiments to insure accurate and representative simulation results, as well as the insights gained through analysis of experimental data. Thus to support the development of improved behind armor injury models, an experimental methodology was developed and executed in which the extent of injuries resulting from residual velocities of ballistic projectiles were directly measured; specifically dynamic pressure and strain during the wound cavity formation, collapse, and final depth of projectile penetration.
