摘 要: | 一点的应力是一个二阶张量,它的九个分量(二个正应力和六个剪应力)是标量,不是矢量。通常把一点的应力向一对正交的坐标轴上投影为和它们是应力的投影分量,也不是矢量。

关 键 词: | 应力 矢量 张量 投影分量 可分解分量 |
Normal Stress and Sheering Stress are Not Vector |
| |
Abstract: | It is wrong that to think the norma stress and shearing stress are vector. Because of the stress is two time tensor,but normal stress and shearing sterss are projecting components of the stress of a point. |

Keywords: | Stress vector tensor projecting component resoluble component |
