本文将第一作者最近提出的纤维复合材料基体中随机界面结构缺陷均匀化的新思想推广到两个部件的接触区。描述了界面缺陷产生的物理机制，并采用随机有限元法（SFEM）对纤维-基体界面缺陷的不同位置进行了测试。计算了位移随机场的两个一阶矩，并提出了一种新的SFEM列式。
In this paper the new idea of homogenization of stochastic interface structural defects in the matrix of a fiber composite, recently proposed by the first author, is extended to the contact zones of both components. The physical mechanism of the occurrence of interface defects is described and different versions of location of these defects on fiber-matrix boundary are tested using the stochastic finite element method (SFEM). Two first moments of the displacement random fields are computed and a new SFEM formulation for such problems is proposed.
