| 摘 要： | 假定位移场,并将位移势函数展开成一系列的特征函数,代入空间轴对称变形的基本方程,推得界面裂纹的特征值理论。把这一理论应用到单向增强的连续纤维复合材料上,建立了纤维断裂、基体开裂等模型下应力奇异性的特征方程,分析了界面裂纹尖端的应力奇异性。 |
| 关 键 词： | 位移势函数 特征函数 界面裂纹 应力奇异性 |

| Abstract: | The displacement field is assumed,and the displacement potential func-tion is expressed in terms of a series of eigenfunctions.Substituting these intobasic equations of space axisymmetric deformation,we obtain the eigenvaluetheory of interface crack.Applying this method to unidirectional long fiber-reinforced composite material,we then have got the stress singular eigenequa-tions of broken fiber model and cracked matrix model,and analyzed thestress singularities at the apex of interface crack. |
| Keywords: | displacement potential function eigenfunction interface crack stress singularity |
