In this paper, two kinds of material model were introduced, based on the same condition, such as explosive, liner structure, Johnson-Cook and Steinberg model were selected for liner. The process of shaped charge jet penetration into target was simulated using ANSYS/LS-DYNA, the results compared and showed that these two kinds of model can simulate the form and penetration process of the jet accurately, and the top velocity of the jet head were almost the same.
