Investigation on the Mechanism and Experiment of Pistol Cartridge Penetrating into Gelatin Target with Soft Body Armor

doi:10.3969/j.issn.1000-1093.2018.01.001

Abstract

Abstract: The destruction forms of soft body armor penetrated by pistol cartridge are analyzed according to the penetration characteristics of pistol cartridge. A motion model of pistol cartridge penetrating into the gelatin target with soft body armor is established by introducing the fiber constitutive model and gelatin elastic model based on the material constitutive model of ultrahigh molecular weight polyethylene. The motion model is calculated by taking two pistol cartridges with the diameters of 9 mm and 5.8 mm as killer elements. At the same time, the numerical calculation and experimental verification are carried out, respectively. The calculated results are compared with the corresponding experimental results. The compa-rative result shows that the motion model can describe the motion of pistol cartridge penetrating into the gelatin target with soft body armor accurately. Key

Key words: pistolcartridge, softbodyarmor, ultrahighmolecularweightpolyethylene, gelatin, motionmodel
