| 摘 要： | 平面温度场的延拓有限元分析 大多数复杂温度场问题的解析解往往是难以获得的,必须采用一些近似的数值计算方法。延拓有限元技术合理利用了单元邻近外点信息,以构造单元内高精度广义插值近似函数,从而在不增加网格剖分单元及结点数目的条件下,有效地改善温度场的分析精度。

| Abstract: | An extended finite element method for two dimensional ten, perature field problems is proposed. The method is characterized by utilizing the information from nodes in external elements to construct approximate functions on the element without additional nodes and elements, the computational accuracy can be improved by the technique. |
