| Abstract: | The penetration process of an explosively formed projectile simulation into water is conducted by using the large-scale finite element analysis software ANSYS/LS-DYNA.The influences of shape and velocity of projectile on penetration is analyzed.The velocity decrease of projectile moving in the water is also studied.Some valuable advices are given for the design of the shape charge configuration of torpedo warheads which have good underwater trajectory characteristics and terminal effect. |
