| Abstract |
The study of cavity morphology forming in behind armor blunt trauma (BABT) is helpful to understand the dynamic process of blunt trauma, and provides an important method for trauma assessment. This study analyzes the impact effects of three types of bullet (9 mm Luger, .45ACP, and 7.62 × 17 mm pistol bullet) on the gelatine’s mechanical response, employing high-speed photography to capture real-time temporary cavity in gelatine blocks protected by soft armor. Regardless of bullet type, the changes of cavity’s profile, depth, radius and volume showed the existence of self-similarity during cavity evolution. While the depth followed an exponential law during the expansion stage, it peaked earlier than the volume did. The analysis of maximum depth (depthmax), energy transfer parameter, volume growth rate, pressure and impulse were compared to study the influence mechanism and discuss the blunt trauma. |
