| 中文摘要: |
| 利用映射函数法将裂纹扩展动域变分问题化为定域变分问题,从最小势能原理出发推出裂纹扩展的递推积分方程,进一步用有限元法求得递推代数方程,用Matlab语言实现了裂纹扩展仿真算法,该算法不必在每次裂纹扩展后中进行裂纹物体的重构和网格的重分,有一定的实用价值。 |
| 英文摘要: |
| The crack automatic growth problem is solved by transforming a domain variation integration into the normal one using a mapping function. The iteration equations for the continuum crack propagation is formulated according to the minimum potential principle. The Matlab implementation is demonstrated for crack growth simulation by the finite element method, and there is no need of updating and remeshing the configuration. This approach has some value in engineering application. |
