层状复合材料结构边缘效应数值分析^*

基金项目: * 中国科学院科学基金

摘要: 为进一步探讨层状复合材料结构边缘效应,我们引用了数值-摄动法,它是基于合成展开和改进的最小二乘加权余量法之耦合.为突出边缘效应,我们着重讨论“边界层”区内的解即所谓内部解.作为例子讨论了两层和四层对称铺设层合结构.

Abstract: In order to further study free edge effect in composite laminates, a new method is developed. This method is based on the perturbation and modified method of least square. In this paper, we emphatically discuss the solution within the boundary layer region, the so-called inner solution. As an example, we will discuss structures composed of two and four symmetric laminates.
