| 摘 要： | 把所研究的弹性域分成若干个子域，然后利用基本解根据边界条件和域与域之间的交界条件建立积分方程，最后采用虚边界元技术进行数值求解．文中除讨论两域耦合情况外，还讨论了任意多域耦合的情况，并给出了形成总体矩阵的一般规律．

| Abstract: | In this paper the elastic domain is divided into several subdomains. The integral equations are then derived by the authors using the fundamental solutions. Finally the equations are solved by the fictitious boundary element method. Numerical examples are given to show that the proposed method can successfully deal with non_homogeneous or non_uniform thickness elastic plane problems. |
