| Abstract: | The penetrating process of a steel ball with high speed in the water and the development of a penetrating passage (namely cavity) are simulated by a two dimensional finite element program. The results of the penetrating velocity of steel ball, the pressure waves in water and the development of cavity are obtained and they are coincident with that observed in the experiment. It is shown that the numerical simulations can be considered as an important method in the study of Wound Ballistics and has a bright future in the practical problem. |
