| 摘 要： | 在对锥形弹侵彻破坏模型分析的基础上，借用Taylor扩孔理论和修正后的Thomson碟型破坏理论，建立了一个针对靶板发生扩孔型和碟型混合破坏的新的能量表达式，利用该式可预测极限穿透速度，并运用具体算例对其进行了验证。

| Abstract: | Based on the analysis of failure model of target penetrated by conical projectile, a new energy function was obtained according to Taylor's theory for ductile hole failure and revised Thomson's theory for dishing failure. The function accorded with the mixture failure model including ductile hole failure and dishing failure. The critical velocity could be predicted by using the function. By using the example the availability of the function was verified. |
