| Abstract |
At present, compound targets are usually used to evaluate the mechanism of weapon injury and killing efficiency as well as the protective performance of soft armor. In order to study the ballistic impact response of the skin-gelatin composite target under the protection of UHMWPE panel, the structural design scheme of UHMWPE panel with different specifications was drawn up and prepared. Ballistic impact experiments were carried out on the UHMWPE panel with 7.62 mm pistol projectile, and the damage morphology, residual velocity and energy absorption mechanism of the target plate were analyzed. The finite element models of 7.62 mm pistol bullet penetrating UHMWPE panel and UHMWPE panel-skin-gelatin were constructed, and the impact response characteristics and damage morphology of the composite target were analyzed under different area densities, incident velocities and angles of attack. The results showed that different specifications and processes will affect the protective performance of UHMWPE panel. With the increase of incident velocity and angle of attack, the concave depth of the panel becomes larger and the damage becomes more serious. Furthermore, in the process of penetration, the constraint definition of the model will affect the stress propagation of the composite target. This study provides a new idea for the evaluation of weapon injury mechanism and killing efficiency and the evaluation of protective performance of body armor. |
