| 中文摘要: |
| 本文用复势理论导出双材料V形切口的特征方程及切口顶端附近的应力和位移场，首次利用数值分析方法计算出了混凝土坝坝踵区的应力强度因子。典型算例表明，本文计算结果具有较高的计算精度。 |
| 英文摘要: |
| The eigen values and the fields of stress and displacement for the bimaterial V-notch tip have been calculated by using complex potential theory. A numerical method is constructed to calculate the stress intensity factors for the bimaterial V-notch and the heel of concrete dam on rock foundation. The soluation is highly accurate. |
