| 摘 要： | 建立横向冲击时易切削钢裂纹扩展的随机分形模型，计算了冲击断口的随机分形维数Ｄ，比较和分析了Ｄ、非随机分形维数与实测分形维数。结果表明随机分形断裂模型与实验数据完全吻合。

| Abstract: | A random fractal model for the crack propagation of free-machining steelsduring impacting transversely was proposed. The random fractal dimension for impact fracture surface was then calculated. And self-similar fractal dimension was also analysed. Experimental measurement is fair agreement with that of random fractal model proposed. |
