| 摘 要： | 矩形截面梁应力极值分析是其强度设计的关键，应用应力状态数值计算的新方法对其进行分析，得到了准确的应力极值分布规律图，采用整体分析的综合方法，利用应力圆的几何分布特点，在图形上就可以准确地判定出应力极值的大小和方位，使得应力极值的分析问题由抽象的计算变得具体而且可视，方便于梁应力极值问题的分析和应用。

| Abstract: | The analysis of the maximum stress on a beam with rectangular section is the key to the intensive design. A new numerical method of stress status is applied to analyze the beam with rectangular section and an accurate distributing regular diagram of stress limitation is obtained. Using characteristics of the stress circle's sketch, dint and directions of the maximum stress could be accurately found by comprehensive method of whole analysis. The distributing regulation of maximum stress could become clear and visual for the sake of the convenience and application. |
