解析研究内部爆炸驱动金属圆筒的运动

A Mathematical Method to Describe the Movements of the Cylindrical Tube Under inside-explosive Loading

从柱壳运动的控制方程出发,应用壳壁发生贯穿破裂的Taylor判据,给出了内部爆炸加载下金属圆筒壳壁的运动轨迹、平均破裂时间、破裂应变、半径及破片初速度的解析表达式。结果表明:计算结果与相关文献中的实验结果基本符合。

Deducing from the dynamic equations of the inner detonation loaded cylindrical wall, along with Taylor's complete fracture law of the cylindrical tube, we get the mathematical expressions of the fracture strain ,the fracture radius,the mean fracture time and the initial velocity of the fragments. The results show that there is a satisfactory agreement between the computations and the experiments.
