| 摘 要： | 基于边界积分方程中被积函数散度为零的特性，提出了弹性力学平面问题的等价边界积分方程的边界轮廓法，该方法无需进行数值积分，只需要计算单元两结点势函数值之差。实例计算说明，基于传统的边界积分方程的边界轮廓法所得到的面力结果是错误，而本文建立的边界轮廓法则可给出精确的结果。 |

| Abstract: | In this paper, the Boundary Contour Method (BCM) based on the equivalent displacement boundary integral equation is presented for two dimensional linear elasticity. This method requires only numerical evaluation of potential functions at the ends of boundary elements. Numerical examples are presented. The present method is shown to give the excellent results. |
| Keywords: | boundary contour method boundary element method elasticity |
