| 摘 要： | 讨论了无限与半无限平面域中线弹性问题的基本解的性态，提出一种修正 Ｋｅｌｖｉｎ权函数，并导出无穷边界元的算式。这种方法特别适用于不规则的半无限平面问题。计算表明，这种计算方法与有限元相比，在保证具有相似精度的条件下能够节省ＣＰＵ时间和数据处理工作量。

| Abstract: | In this paper, the behaviours of the fundamental solutions for elastic problems in infinite and semi-infinite plane domain were discussed. A modified Kelvin weighting function was presented and thus the formulations of infinite boundary elements were derived. This method is particularly suitable for solving problems of irregular semi-infinite plane domains. The results showed that this technique could significantly save CPU time and data preparations in the condition of having a similar accuracy compared with the finite element method. |
