| Abstract: | The comparability rule on hydrodynamics impact was described and validated with the dimension analysis method.The modified SPH method was used to simulate the thin target penetration to evaluate the comparability rule.It is demonstrated that the comparability rule on hypervelocity impact is accurate and feasible and it is significant for the experiments. |
