Numerical and Experiments Investigations on Armor-Piercing Characteristic of Jet under Different Standoff Distance
In the present study, a lot of numerical analysis and experiments were performed to investigate the penetration power of jet under great standoff distance. In the Numerical simulation, the finite element model was built based on the representative shaped charge. Through computation on nonlinear dynamics AutoDyn program, the penetration characteristics that jet shaped by representative charge impact on the semi-infinite steel target and interval plates under different standoff was obtained; base on these, under the same condition, the static explosive experiments that the jet impact on the interval plates under different standoffs were done, the variety rule between the standoff and layer number penetrated by jet was obtained. The outcomes between experiments and numerical simulation were consistent. It was indicated that the numerical simulation method was correct and available.
