| 摘 要： | 本文利用弹性力学中的Ｇｏｕｒｓａｔ公式，具体地给出了具有任意接合角的异材界面端附近的奇异应力场和位移场；所得到的关于应力奇异性次数的特征方程，与Ｂｏｇｙ利用Ｍｅｌｌｉｎ变换求得的结果完全一致。本文的结果还表明：材料常数对接合材料力学性能的影响可只用两个组合参数来描述。

| Abstract: | It seems that the singular stress field at the interface edge has very important application in the strength evaluation of bonded dissimilar materials. This paper presents an eigen equation which determines the stress singular order and the details of stress field as well as displacement field around the edge point. This paper also points out that the mechanical response of bonded dissimilar materials can be described by only two composite parameters in the case of absence of initial stress. |
