Abstract |
Understanding the transient cavity formation and transient pressure in the behind armor blunt trauma (BABT) is of fundamental importance in various research fields. In this paper, the transient response of ballistic gelatine behind the soft body armor subjected to the impacting of pistol bullets was studied. The profiles of the transient cavity in real time were captured by a high-speed camera, while the transient pressures were simultaneously recorded by pressure gauges. We find the cavity expansion-contraction movement is self-similar and can be expressed as a semi-ellipse. The gauges-recorded pressures reveal that three peaks on the pressure-time curve.
