| A comparative study has been carried out of the processes of impact and penetration into soil medium of axisymmetric spherical and conical projectiles on the basis of the Godunov numerical method and the local interaction model. The model applicability error has been shown to be determined by the ratio of maximum and quasi-stationary values of penetration-resistance forces. |
