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
Based on the characteristic that the integrand divergence is zero in the boundary integral equation, the boundary contour method for the equivalent boundary integral equation of the elastic mechanics plane problem is proposed. The method does not require numerical integration and only needs to calculate the value of two node potential functions difference. The example calculation shows that the boundary force contour method based on the traditional boundary integral equation has the wrong result, while the boundary contour method established in this paper can give the accurate result
