摘要
本文在系统介绍国内外学者研究脱层现象的机理—边缘效应之后,提出了利用数值—摄动法来分析边缘效应,不但详细讨论了所谓Pagano-Pipes问题,还讨论了受弯层合板的边缘效应问题。利用合成展开法,将求解区域分成内部区域和边界层区,导出了内部解和外部解的数学模型,并以边界积分方程的形式给出内部解。
After introducing some workes about edge effect in internal and abroad, a new method is developed, it is based on perturbation and composite expansion, the solving domain is divided into two different regions, i. s. the interior and boundary layer regions. The mathematical model for the inner solution and the outer solution are yielded, the inner solution is expresed with boundary integral equation.
