For the established scaling-shrank model of composite armor, the damage process of the hemispherical shaped charge acting on the composite armor structure was simulated by using AUTODYN software based on the algorithm of multiple substance fluid-solid coupling. Numerical results match the experimental data well. Besides, the damage characteristics of shaped charge to the pressure-resistant and pressure-nonresistant shell were investigated as well as its destructive form to the after-effect armor. This work can serve as a reference to the damage assessment of the underwater weapons with shaped charge acting on the double-shell submarine and to the anti-shock research and design of the warships.
