| 摘 要： | 本文对含有边缘界面裂纹的不同正交各向异性平板在反平面载荷作用下的位移场与应力场进行了分析,得到了满足所有基本方程以及裂纹面边界条件与交界面连续条件的位移场与应力场展开式,本文进一步应用变分原理决定应力场展开式中奇异项系数—应力强度因子,计算结果表明,应力强度因子的收敛性是令人非常满意的.

| Abstract: | In this paper,the express of the stress and displacement field of a dissimilar orthotropic laminate with an interfacialedg crack(delamination),under antiplane shear loading,satisfying all of the basic equations,boundary conditions along the crack surfaces and conditions of continuity along the ligament of the interface are obtained by the menthod of complex variable.Furthermore,the coefficient of the singular term(stress intensity factor) is determined by the variational method for multi-regions.The computation results show a satistactory convergency of the stress intensity factors and the calculation is very time-saving. |
