微裂纹扩展中的分形现象及其计算机仿真

Fractal in Propagation of Microcrack and Its Computer Simulation

本文探讨了采用仿真技术研究微裂纹连接过程和生成分形断口表面的可行性，发展了用于仿真微裂纹随机生长行为的ＧＯ（ＧｒａｏｔｈＯｒｉｅｎｔｅｄ）模型的基本构想，并进行了计算机仿真实验，由此得出了一些有益的结论。

The feasibility of employing simulation technique to study the linking process of microcracks andgenerating rules of fractal fracture surface is explored in this paper.A revised Go model is proposed tosimulate the above mentioned process and a number of helpful conclusions have been drawn from thesimulating results.
