轴对称旋转薄壳几何不连续处的应力分析及应用

The Stress Analysis and Its Application of Rotationally Symmetrical Shell at the Geometrical Discontinuity

通过薄膜应力理论及简单边界效应理论 ,分析并求出了轴对称旋转薄壳几何不连续处的应力计算公式及所需满足的条件。在此基础上 ,对不等厚筒体三种过渡段壁厚变化梯度进行了分析 。

The stress calculation formulas were put forward and analysed through the theories of membrane stresses and simple periphery effects. On this basis, three kinds of transitional thickness gradient changes of unequal thickness shell were analysed and some relevant conclusions were drawn.
