Gun Bullet Collision and Penetration Behaviors for Protecting Board

Abstract:

In this research, the bullet-collision test was done in the different velocity. The influence of its velocity on the deformation shape after collision was discussed by comparison with experiment and simulation. The velocity of the bullet was chosen in several kinds of speed ranges at 80m/s-250m/s. The angle of incidence with the collision object is 90 degree (head-on collision). The deformation shape was measured by 3D measurement instrument and reconstructed with 3D-CAD based on the 3D digital data. The deformation mark of the polycarbonate plate and the penetration shape of acrylic plastic plate caused by the bullet's collision with the object were examined. In addition, the collision simulation of the bullet was done by using FE analysis code “LS-DYNA”, and these analytical results were compared with the 3D digital data which is the experimental results.
