摘要
本文利用解析方法，建立了球形容器角变形的一些几何关系式与局部应力的分析表达式；求得了一个简明而且实用的应力集中系数公式，表明应力集中不仅依赖于角变形量，而且随径厚比的平方根的增加而增加．
In this paper several geometrical relations of angular deformation and the analytical expressions of local stresses in spherical vessels are established by analytical method. A concise and practical formula for calculating the stress concentration coefficient is derived, which shows that the stress concentration is related to angular deformation and increases with an increases of the square root of the ratio of radius to thichness.
