Abstract

To investigate the internal pressure transmission in body caused by the small caliber projectile under non-penetration, the non-penetration firing tests were conducted with different impact velocities and different protected targets including Landrace and gelatin to measure the pressure value in the targets at different locations by dynamic acquisition system of pressure. The results show that the pressure is higher when the impact velocity becomes greater, and the peak pressure decays exponentially with the distance between impact point and the measurement position, and the pressure attenuation speed in the Landrace is greater than that in the gelatin target, and the energy absorption ability of skin has great relationship with impact velocity. The test results have important significance in the wound treatment, the injury standard establishment, and the bullet design modification.
