各向异性复合材料的应力奇异性

SINGULARITIES IN ANiSOTROPIC COMPOSITES

本文根据各向异性材料的特征值与特征函数理论,用极其简单的矩阵形式,建立了复合楔形和裂纹止于两材料界面等情况下确定应力奇异阶次的特征方程,讨论了应力奇异性的一些特性,计算了各种情况下的应力奇异阶次。

In this paper, according to the theory of eigenvalue and eigenfunctionexpansion in anisotropic materials, using very simple forms of matrices, the eigenequations of stress singular orders are established on laminar wedges and cracks terminating at interface. The stress singular characteristics are discussed, the stress singular orders of all cases are calculated.
