| Abstract: | This paper introduces explicit arithmetic of explicit dynamical analysis software package LS-DYNA.Two-dimensional numerical simulation of the jet formation of linear shaped charge blasting had been made using ANSYS/LS-DYNA code.This paper discusses the results of numerical simulation,compares the results obtained from two-dimensional numerical simulation of jet formation of two linear shaped charges with different detonation velocities.The results of numerical simulation are in agreement with physical phenomena and laws of jet formed by linear shaped charge blasting.The study indicates that the calculation model and simulation method are reasonable and feasible,so can be applied to the optimizing design for linear shaped charge cutter. |
