摘要
在基本解的基础上，研究了正交各向异性复合材料平面问题边界元法的有关基本问题，包括Ｃ矩阵、Ｇ（ｉｊ）矩阵、Ｈ（ｉｊ）矩阵和域内应力表达式等，并建立了常值边界单元和线性边界单元的计算公式（适用于各类边值问题）。用建立的公式对正交各向异性极含中心裂纹问题和含圆孔的无限大正交各向异性板问题进行了分析与计算，取得了较好的计算效果。
Based on the fundamental solution, some basic problems of the boundary element method on orthotropic composite material plate including C mains, G(ij) matrix, H(ij) matrix and stress formulae of internal region are studied. The calculation formulae of the constant boundary element and liner boundary element are built up.The theory and formulac are suitable for various boundary problems. Aocording to the formulae, an analysis for orthotropic plate with central cracks and infinite orthotropic plate with round holes is presented.The calculating result is satisfactory.
