Abstract：Aiming at a flat-nosed projectile with high velocity impacting a ceramic composite target, the calculation model based on the lumped mass method was improved by considering target's internal friction effects. The theoretical computing model for the projectile's penetrating process was established and the algorithm was developed by using MATLAB to calculate the depth of the projectile's penetrating the ceramiccomposile target under different impact velocity. The results were compared with those of tests and those of numerical simulation with AUTODYN, they agreed well each other. Parametric analysis results showed that the anti-penetration ability of the composite target can be improved with increase in thickness of ceramic; the growth curve of the projectile penetration depth becomes flat with increase in initial impact velocity.
