容器设计中边缘应力的处理

On Treatment of the Edge Stress in the Vessel Design

分析边缘应力的性质,特点及其与薄膜应力的区别联系,指出边缘应力与压力容器强度的关系,提出了容器设计中处理边缘应力的几种方法和具体措施。从而解决容器设计中一个不容忽视的重要问题。

This paper first analyses the nature and features of the edge stress, and its differeces from and its relationswith the film stress, then points out the relationship between the edge stress and the strength of pressure vessel, andputs forward several detailed measures to treat the eege stress, and therefore solves the important problem in the ves-sel design.
