The physical and computational models of explosive damage effect of obstacles in water are proposed. The conservation equations, the dynamic elastic-plastic constitutive relation and damaging criterion of concrete are established, together with the yielding criterion subjected to large strains, high strain rates and high pressures. Meanwhile, based on the multi-material Eulerian algorithm, the NM-MMIC code, which is a general 2D multi-material elastic-plastic hydrodynamics code with C++ language, is applied to simulate the damaging effects of obstacles in water by explosion with different charges and at different positions. The whole process of underwater explosion are visualized by VISC2D code. The pressure variation of the side of the obstacle facing to the explosive are demonstrated quantitatively. The optimum damage charge is obtained. The damaging degree, and the damage laws of the obstacle in water are evaluated. These results are valuable in designing and estimating ammunitions against obstacles in water.
