3 Numerical Simulation Results and Analyses

By numerical simulation of the armor-piercing warhead penetration the steel target,
influent rule of different k value gridding side length to the armor-piercing warhead
penetration velocity and deepness, damage area of the target and numerical simulation
efficiency was acquired

3.1 Effects of Gridding to the Armor-Piercing Warhead Penetration Velocity

and Impulse

Fig.3 showed the armor-piercing warhead velocity along with time change course curve
in different k value.
Fig.4 showed the armor-piercing warhead impulse along with time change course
curve in different k value.
