Analysis of Aperture Shape Changing Trend Base on the Shaped Charge Jet Penetration through the Steel Target

Based on the characteristic of the linear shaped charge and the theory of jet penetration target, a method, which adopts explicit dynamic analyzing program AUTODYN to simulate the process of the linear shaped charge jet penetration through the target, is proposed in this paper. The trend and rule of aperture size changing with time during the process of the jet penetration the target, are analyzed. The physics phenomena and rule are basically same between emulational result and testing result. It shows that analytical model and emulational method are reasonable and practical.
