| Abstract: | The software of LS-DYNA was used to analyze 70mm EFP penetrating 40mm thickness 45 # steel target, The forming, flying and penetrating steel target characteristic of the arc-taper EFP was studied. The result of numerical simulation was in accordance with the experiment. It shows the numerical simulation is right and the analysis is reasonable. It provides the way to study are-taper EFP and the valuable rule. |
