Influence of Collision Velocity and Angle on Bullet Deformation Investigated by Reconstruction and FEM Analysis

Abstract:

In this paper, the effects of collision velocity and collision angle on bullet deformation were discussed and performance of protection board made of PC (polycarbonate) plate was estimated. After gun firing experiments, the shape of the bullet and PC were measured using three dimensional measurement machine and deformed the bullet and PC plate shapes were reconstructed by using 3D-CAD as digital data. Furthermore, crash simulation of the bullets were performed by FEM analysis code “LS-DYNA”, and the results of simulation and measurement were discussed.
