| 中文摘要: |
| 为更好地分析表面裂纹,本文利用拟协调元方法,提出了一个高效率、高精度的三维奇性单元。并选用了一个较好的外接单元,分析了一个真实的管节点,给出了和实验吻合较好的结果。 |
| 英文摘要: |
| A efficient and accurate three-dimensional singular element is proposed based on Quasi-conforming technique for analysis of crack. By using a suitable exterior adjacent element,a tubular joint with a surface crack has been investigated. The results are good compared with that of the experiment. |
