数值流形方法物理覆盖系统的自动剖分

Auto Mesh Algorithm of the Finite Cover System in the Numerical Manifold Method

利用面向对象设计思想将岩土力学中数值流形方法的物理覆盖系统抽象为独立的数据类，在此基础上完成了物理覆盖系统的自动剖分算法。对裂缝切割的连续材料，在裂缝的扩展过程中能自动生成正确的流形单元。算例表明，本算法是可靠和有效的。

A auto mesh algorithm of the finite cover system is presented by abstracting the finite cover system of numerical manifold method as independent data classes.The programs are made by Object Oriented Programming(OOP).The accuracy manifold element can be generated automatically when the continuous material is cut by crack.The calculation result shows that the algorithm is reliable and effective.
