This study is aimed at the relation between maximal penetration depth and impact velocity for a long-rod penetrator vertically penetrating a semi-infinite target. The effects of impact velocity on the maximal penetration depth are obtained by numerical simulation. The results show that the threshold velocity exists in the process of penetrating due to the target strength and the interfacial effect, and the penetration enters into the quasi-steady stage from the dwelling stage only as the impact velocity of the penetrator is beyond this value, which is the key reason why the penetration depth does not change or increases extremely slowly with increasing impact velocity when the impact velocity is small compared with the threshold velocity. The penetrator velocity and penetrating velocity are close to a constant in the quasi-steady stage, and the positive linear relation between them is only related to the strength properties of the penetrator and the target, which is the main reason why the penetration depth linearly increases quickly with the impact velocity increasing when the impact velocity is beyond this threshold velocity.
