| 摘 要： | 本文用有限元方法分析了无限大平板内有三个等椭圆孔当承受单向和双向均匀拉伸载荷时,孔边的应力集中问题,计算结果分别用不同受载情况下,三孔应力集中系数相对于单孔应力集中系数的比值与孔间距无量纲参数的关系曲线给出,该曲线表明了三个椭圆孔之间的应力集中干涉效应。

| Abstract: | The stress concentration of three-equal elliptical holes in an infinite plate under uniaxial and Biaxial tension is analysed by using finite element method. The results are given by curves platted in terms of the dimen-sionless parameter of the ratio between the diameter of holes to center distance Vs and the ratio between stress concentration factor of the three-equal elliptical holes to that of a single elliptical hole.From the curves the deviations of stress concentration factor due to the influence between elliptical holes are clearly expressed. |
