摘要
本文对边界元──有限元耦合方法分析二维弹性力学问题进行了探讨。采用非连续元离散边界积分方程，解决了耦合分析中的自由度约束问题。给出了利用非连续元实现边界元──有限元耦合的具体步骤。数值算例表明了本文方法的有效性。
An analysis of BEM-FEM coupling procedure is presented in this paper. Discontinuous element is employed to discretize boundary integral cquations to circumvent freedom constraints in coupling approach. Several techniques for solving coupled algebraic equations are implemented in the proqram developed by the author. Some numerical results are given to illustrate the feasibility and efficiency of the approach proposed.
