摘要: 本文讨论了二维有限元网格的生成方法,研究了结点连元法,改进了非随机结点产生过程,并将它应用在含裂纹飞机结构件的有限元分析中。同时提出了一种实现加密区向非加密区过渡的方法。Abstract: Methods of 2D finite element mesh generation are reviewed. Special attention is paid to the node connection approach, where the nonrandom node generation technique is improved and applied to the aircraft structure containing cracks. A method for constructing the transition area between the fine mesh region and the normal ones is also presented.
