    Abstract
  • The complex physical process is always accompanied with hypervelocity impact. In this paper, the physical process of rod-shaped cylindrical tungsten alloy bomb impact thin steel target has been studied. The impact process model and fluid dynamic information of every particle were obtained by means of AUTODYN/SPH method and the fragment particles were identified through range search and fragment identification program. Some information of the elastic target change process, the number of the target fragment, the change of the relative energy with the time during the impact were obtained by MATLAB. It is found that with the increase of impact speed, the residual body is eroded seriously, and the energy loss of missile body is increased, and the energy of the body loss is mainly converted into the kinetic energy of the bomb target. The energy loss histogram of the impact at the time of 20 μs and energy change process for the target plate impacted have been analyzed.
