| 摘 要： | 考虑物体边界对有限二维及三维裂纹体的影响，给出满足边界条件的应力强度因子解析解通常是非常困难的。以圆柱钱币裂纹的应力强度因子为例，提出了裂纹张开能量释放率求解应力强度因子的方法———Ｇ积分法，该方法不仅可以求解二维裂纹体的应力强度因子，也可以用于三维裂纹体的应力强度因子。 |
| 关 键 词： | 应力强度因子；断裂；力学 |

| Abstract: | Because of the affection of cracked member boundary, it is usually difficult to give a closed form of solutions of stress intensity factors. In present paper, take the penny shaped cracks in cylinder as an example, a method of G*-integral is proposed. This approach shows that the G*-integral can be used to analyzes not only the two-dimensional cracks but also the three-dimensional one. |
