| 摘要: |
| 试验研究了穿甲子弹垂直侵彻高强防弹钢的机理,提出了一个分析靶板极限速度和弹体剩余速度的理论模型,该模型综合考虑了材料的应变率与热软化效应,结果表明,理论值与试验值吻合很好。分析了失效准则的影响,研究了剪切带温度和靶板耗能随入射速度的变化规律。 |

| Abstract: |
| The perforation mechanism of the high-strength armor by Armor Piercing Bullet (AP) was investigated by experiments. A theoretical model for the ballistic limit of the armor and residual velocity of the bullet including the effects of the strain rate and the thermal softening of the material was presented. The results show that the theoretical values have fine agreement with those of the experiments. The impact of failure criterion on the results was analyzed and the temperature rising of the shear band and the change rules of energy-dissipating of the target with the input velocities were discussed. |
