Abstract
This paper adopts ANSYS / LS-DYNA to make a numerical simulation on the anti-penetration performance of High Density Polyethylene (HDPE) honeycomb protection structure. It is discovered by analyzing the projectile body’s penetration trajectory that the projectile body deflects away at a certain angle after intruding into the protective structures. There is a certain vector displacement between where it ultimately stays and the invaded position. And beyond that, this paper probes into the impacts of HDPE film thickness and projectile initial velocity on the anti-penetration of honeycomb structures. The results reveal that the aggradation of the HDPE film in a certain range can effectively reduce the penetration depth of the projectile, however, if beyond a certain range, it is not obvious to play an effect on reducing the penetration depth of the projectile. The honeycomb structure has a better anti-penetration to the projectile in a certain initial velocity range. All in all, it has a brilliant prospect for future application.
