| Abstract: | Numerical simulations of tungsten long rod penetrating into confined ceramic target was carried out by inserting the constitutive models of ceramic and metal in the SPH/FEM coupling method. The penetration pattern was reproduced and the property of anti-penetration of ceramic targets was discussed. The computational results for different impact velocities were compared with the experiments. The penetration depths of computations are in good agreement with the experiments and so that the coupling method is validated. |
