Ceramics materials have been widely used in military projects, aerospace, aviation and ship structure protection, due to their good mechanical properties such as low density, high strength and high sound velocity. The destructive process of alumina ceramic impacted by a tungsten alloy projectile is simulated using smoothed particle hydrodynamics (SPH) techniques of AUTODYN. The simulation results are consistent with the experimental results, which indicate that the method is feasible and effective. The method proposed provides a convenient and economical way to study the failure behavior of alumina ceramic under strong impact loading.
