| 摘 要： | 应用复变函数方法,通过构造复函数形式的特解序列,从理论上研究了顶端受集中力偶的双材料平面界面接合楔体的应力场,给出了相应的经典解,发现其存在一次和二次佯谬,相应的应力具有(Inr)／r2和(In2r)／r2的奇异性。

| Abstract: | By employing the complex variable methods and constructing the particular solution sequences in the form of complex functions, a study on the stress field in an interface edge consisting of two bonded dissimilar materials subjected to a concentrated couple on apex was provided, the corresponding classical solutions were obtained, the primary paradox and second paradox may occur, and the corresponding stresses possess the singularity of (Inr)/r2 and (In2r)/r2. |
