The EFP formation with Hemispherical Liner is simulated using 2-D axisymmetric lagrangian code provided by LS-DYNA. The criterion of numerical method is discussed, and the typical processes of EFP formation, velocity and kinetic energy are studied. Differences between 6 models are analyzed, and the calculated results are in good agreement with the experimental observations.
