Impact Performance Comparison of B4C, SiC, and Al2O3 Ceramics with Varying Surface Angles and Velocities
Abstract
The paper describes a study on the impact performance of three different ceramic materials with varying surface angles and impact velocities. Finite element analysis was performed to obtain data on projectile residual velocity, absorbed energy values, and damage data on the plates. Boron carbide and silicon carbide showed better impact performance than alumina, and increasing surface angle reduced projectile residual velocity. The amount of absorbed energy decreased as impact velocity increased, but it increased by an average of 8% when the plate surfaces were inclined. This phenomenon can be explained by the geometric nonlinearity in the ceramic plate, which changes the direction of movement of the projectile and causes differences in the damage formation in the target plates. The damages occurred in ceramic plates were obtained through fragment plotting method, and the ceramic plates were visualized to show the damage structures. The use of an inclined plate provides higher efficiency in alumina samples at high speeds, while the efficiency provided by the oblique surface decreases as the impact speed increases in silicon carbide and boron carbide plates.
