| 摘 要： | 本文从弹性力学三维问题柱坐标下以位移分量表示的平衡方程出发,用小参数摄动技术提出了平面轴对称变温场下包覆金属层压板孔边层间应力奇异性的具体分析方法,得到了确定奇异性阶次的特征方程,并对两种工程实际中应用的含圆孔的层压板作出了数值算例。

| Abstract: | Based on the equilibrium equations expressed by displacement components in cylindrical coordinates for three dimentional problems of elasticity, in this paper a small parameter pertubation procedure is adopted to analyze the stress singularity at edge of circular hole in a laminated metal plate under changed temperature, and the characteristic equation to determine the order of stress sigularity is acquired afterward. Moreover, two numerical examples of laminated plates with hole applied in engineering are presented simultaneously. |
