In this paper, an analytical model has been developed for modeling high-velocity impact on ceramic/nanocomposite targets. In this model, the penetration resistance of the ceramic is determined based on the cavity expansion analysis. Also semi-angle of the ceramic conoid is modified. For modeling the back-up composite laminate, the kinetic and strain energy of yarns and shear plugging have been determined. Also the effect of nano-zirconia particles dispersed in the matrix of back-up composite, based on the ballistic performance of the ceramic/nanocomposite target, is investigated. Ballistic impact tests were performed to validate analytical predictions. Experimental results revealed an improvement in the ballistic performance of samples with nano-zirconia particles. The analytical predictions of ballistic limit velocity and residual velocity of projectile are found to be in good agreement with the experimental results.
