| Abstract: | In order to research the blunt impact effect of target-entry parameters of pistol bullets, the finite element models of the soft upper body of the pistol blunt with a soft-protected human body are developed. By hitting the heart, lung, liver and stomach at three target-entry velocities, the impact response of pistol bullet impacting on human torso with soft armor is numerically calculated by finite element method. The simulation results quantitatively reveal the pressure transmission mechanism of the human body with blunt body armor at different target speeds and positions and the law of blunt impact response at different target entry parameters. The basic data are provided for impact effect analysis and damage assessment with soft armor. |
