Abstract

Due to high hardness, low density and heat resistance, ceramics are widely used in armor applications and industry, thus, in this study perforation process of projectile into CERAMIC TARGETS is investigated analytically and numerically and a modified model is developed. In the analytical section, Woodward’s theory, one of the important theories in perforation process of projectile into CERAMIC TARGETS, is investigated and some modifications are applied in WOODWARD’S MODEL, hence the ballistic results of analytical method are improved and the modified model shows good agreement with the experimental results. However, in the analytical section, the modified model is based on WOODWARD’S MODEL and modification of semi-angle of ceramic fracture cone, erosion, mushrooming and rigid form of projectile and also changes in yield strength of ceramic during perforation process, damage is considered. In the numerical section, a finite element model is created using Ls-Dyna software and perforation process of projectile into Ceramic-Aluminum target is simulated. The results of the analytical method and NUMERICAL SIMULATION are compared to the results of the other investigators and results of modified model show improvement in prediction of ballistic results.
