| 中文摘要: |
| 本文讨论了在结构重分析中局部网格细分时，修改区域与未修改区域交界处的位移连续性问题．文中提出了广义主从控制的概念，把边界上的新增节点作为从节点，同时受多点控制，保证了结构的连续性，并对有限元结构中的常见单元给出了边界的位移控制关系，而且此关系已应用于DDJ程序系统，实现了算法及程序设计． |
| 英文摘要: |
| This paper discusses the displacement continuity on the boundary between modified area and unmodified area. In the process of local grid subdivision of FEM structure,a general master-slave relationship is presented, treating the newly produced nodes as slave nodes contemporaneously controlled by several nodes to ensure the displacement continuity. The displacement control relationships for usual elements are offered,which have been applied to DDJ system. |
