  • The interactions between the high-speed waterjet of 500 m/s and the condensed explosive have been simulated by LS-DYNA3D code with Lagrange method. The pressure distributions in the explosive at different times and the pressure histories at different elements of the explosive have been calculated. On the basis of numerical simulation, the sound speeds of the explosive have been determined. The numerical simulation results accord with the theoretical analysis. During the process of the interaction between the high-speed waterjet and the condensed explosive, the numerical simulation results show that the pressure decreases with the increase in the radial distance of the element and the maximum pressure occurs nearby or in front of the head of the penetrating waterjet.
