Research on Numerical Simulation of Anticartridge Effect for Certain Aluminum Alloy Armor Plate

Because of its specific protective performance, high strength aluminum alloy has been widely used as structural material for light armored vehicle. Based on the experiments, the process penetrating the target plate was simulated by using the method of finite element. Choosing the material model and the algorithm, three dimensional numerical simulation of anticartridge effect for certain aluminum alloy was realized and the parameter variation was demonstrated during the armor-piercing process. The regular pattern obtained from simulation is in accordance with that of obtained from testing. The results show that this material is effective on resisting the attack of bullet.
