Abstract

This research report presents a numerical simulation of projectile impact on a rubber panel. The simulation is conducted in order to explore the possibilities of using rubber panel as additional safety device to sand materials which are currently used as “End Butt” at the 600 meters closed shooting range of Weapon Technology Division (WTD), STRIDE. The rubber panel should be able to stop and trap the bullet and should be light enough to be transferred from one position to the other position in the shooting range. Through simulation, we investigate the capability of rubber panel in resisting penetration of the bullet. The geometry and configuration of rubber panel capable to stop and trap the bullet are proposed. The proposed rubber panel should be suitable to be used in the shooting range. The numerical simulation is conducted using a commercial finite element code MSC. Dytran program which is available at WTD, STRIDE. The solver Lagrangian explicit method is used in the simulation and the failure behavior of contact problem is treated using Adaptive Contact Master-Slave Surface. The simulation result shows that the rubber panel is a potential material to be selected as additional safety device provided that appropriate geometry and configuration of the panel are chosen.
