Simulation Research on Pistol Bullet Penetrating Gelatin Target with Soft Body Armor

Abstract

For pistol bullet, a nonlinear modeling method is introduced to simulate the physical process of pistol bullet penetrating the gelatin target with soft body armor. The velocity, equivalent stress in the gelatin, displacement, acceleration curve is obtained by simulation, then predicts blunt damage effect by analyzing mechanical responses of gelatin with body armor to non-penetrating ballistic impact, the method can be widely applied in the design and evaluation of different bullet and soft protection performance, it has important guiding significance for design and development of small arms wound and equipment of protecting body.
