Abstract: Naval gun guided projectile is an important direction of the development of naval ammunition, which can effectively enhance the capacity of firepower support and anti-missile. Penetration damage of naval gun guided projectile to typical anti-ship missile in proximity mode is researched in the paper. Damage of the two different damage elements (fragment and discrete rod) to warhead cabin of missile is simulated with ANSYS/LS-DYNA finite element analysis software and analyzed. Its useful to the study of the further model of vulnerability analysis of whole anti-ship missiles and offer theory reference to enhancing the damage effect of naval gun guided projectile.

Abstract: In this paper, the three-graded random aggregate model of concrete beam is established by using the Monte Carlo method. And in order to close to the engineering practice, the initial imperfection is putted in to this model. Then the impact load is applied to the beam, and the numerical calculation is carried out, the results of numerical simulation and experiments of previous are compared. It is found that the damage process of concrete and calculation results are similar to the experimental results of previous. Thus proof that the model is suitable to the engineering practice.
