摘　　要：采用影响系数法对膜-基复合材料的界面剪应 体,利用其平面边界作用单位力时的位移场解析解,力三维半解析进行了分析研究.利用三维有限元方法 得到基体的影响系数.结果表明,对膜-基复合材料对薄膜的影响系数进行了计算.将基体作为半无限大 界面剪应力进行三维半解析计算,克服了完全用三维有限元对其进行计算的限制,为该类问题的分析提供了新的途径.The influence coefficient method is ap-plied to study the three-dimensional semi-analytic interfacial shear stresses of film-substrate compos-ite. The influence coefficients of the film are calcu-lated by using the three-dimensional finite element method. The substrate is regarded as a half space. The influence coefficients of the substrate are ob-tained by using the analytic formula of displace-ment on the boundary of the half space, acted with a unit force. The interfacial shear stresses of the film-substrate are thus obtained by three-dimensional semi-analytic analysis, where the three-dimensional finite element analysis can be avoided. It provides a new approach for such problems.
