采用复变函数方法,结合计算软件的符号运算系统对椭圆型孔口周围应力场进行了推导,得到了椭圆周围全空间应力场的解析表达式,并对外载荷沿着椭圆长轴的情况进行了仿真分析。结果表明：随着场点与坐标原点距离增大,相应的应力逐渐降低;当场点与坐标原点的距离远大于孔口限度时各应力分量都趋于定值;对与坐标原点距离相同的场点的各应力分量值有一定的起伏和对称性变化的特征。

The formula for the calculation of stress field around the elliptic hole was deduced by using complex function method and the symbols operation system of calculation software.The computer simulation was carried out under the circumstances that the loading direction is along the major axis of the ellipse.The results expatiate that the stress values become small with the increase of the distance between the origin of coordinates and the referred field points.The stress values approach fixed value when the distance becomes much bigger than the dimension of the hole.For the referred field points with the same distance to the origin of coordinates,the stress values fluctuate and show some symmetrical characteristics.
