    Abstract
  • Numerical simulation of the penetration of tungsten alloy long rod into semi-infinite armor steel targets is performed with ALE method and Steinberg constitutive model coupled in ANSYS/LS-DYNA finite element code. The configurations of four different phases in the penetration process and the changes of relevant physical parameters with time are given. The distribution of pressure, particle velocity and the material flow characteristics of both the penetrator and the targets are analyzed. It is revealed that the numerically predicted depth of penetration is in good agreement with available experimental results and that the behavior of materials adjacent to the interface of penetrator and targets is controlled mainly by the hydrostatic pressure.
