## A Domain Decomposition Algorithm With Finite Element-Boundary Element Coupling

• 摘要: 提出了一种有限元-边界元耦合分域算法．该算法将所分析问题的区域分解成有限元和边界元子域，在满足两子域界面上位移和面力协调连续的条件下，通过迭代求解得到问题的解．在迭代求解过程中，引入动态松弛系数，使收敛得以加速．该方法在两子域界面上有限单元结点和边界单元结点的位置相互独立，无需协调一致，对诸如裂纹扩展过程的模拟具有独特的优势．用所提出的耦合算法分析算例，得到的结果与有限元法、边界元法和另一种耦合算法的数值计算结果一致，验证了这种算法的正确性和可行性．
