摘要
本文利用小参数摄动方法,从一般情况出发,建立和完善了含圆孔层合板孔边层间应力分析的边界层理论,使问题转化为一系列位于孔边径向截面的广义平面问题的组合。 同时,还建立了确定孔边层间应力奇异阶次的特征方程,所得结论适用于含圆孔层合板面内任意受载情况。
The analysis of interlaminar stresses around a circular hole in laminate plate is a complicated problem. In this paper, according to perturbation procedure, the general boundary layer theory for composite laminate with a, circular hole is developed, and the eigen-equations of singular orders of the interlaminar stresses are established. It is found that the problem can be transformed to a series of generalized plane problems.
