Effects of Ceramic Particle Reinforcement Distribution on the Penetration of FGM Armor

Abstract:

In this paper, ANSYS/LSDYNA software is used to simulate the process of armor-piercing projectile vertical penetrate metal matrix functionally graded material (FGM) armor reinforced by ceramic particles with the distribution of two power-law function along the thickness direction. The ceramic particle volume fraction varies from layer to layer along the armor thickness while ceramic particles total volume fraction remains unchanged. Four different ceramic particles distribution armors with the same total volume fraction are simulated. And the effects of the two power-law function types on the penetration of functionally graded material armor are investigated. The results show that the ballistic resistance of ceramic particle reinforced functionally graded armors is better than homogeneous ceramic particle reinforced armor with the same total volume fraction. Meanwhile, the larger the ceramic particles volume fraction on target surface is, the better ballistic resistance of functionally graded armors will be.
