【Abstract】 A threedimensional numerical model is built up by a finitedifference scheme in Eulerian cells to disperse control equations according to empirical formula that describes the material and hydrodynamic basic principles. An interface disposing technique is discussed through Youngs method. A metal projectile is simulated to penetrate concrete target. By the simply analysis of the results; it is true that the numerical simulation inosculates some phenomena of projects.更多还原
