Abstract

For the established scaling-shrank model of composite armor, based on the algorithm of multiple substance fluid-solid coupling, the damage process of the hemispherical shaped charge acting on the composite armor structure is simulated by using AUTODYN software and the numerical results match the experimental ones well. Besides, the damage characteristics of shaped charge to the pressure-resistant and pressure-nonresistant shell are investigated as well as its destructive form to the after-effect armor, so as to 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.
