含裂纹结构的断裂监测与预警

The fracture monitor pattern of the mechanical structure on complex work condition

通过对断裂问题一些基本理论的分析 ,提出了含裂纹结构的断裂监测与预警的方法。该方法是通过测量主应力的大小 ,并把主应力与临界应力值相比较 ,若主应力超出临界值 ,则报警器报警。这样使得结构一直处于安全状态下 。

In this paper, based on the analysis of the fracture question's some basic theory, the Real time monitor pattern of the structural principal stress is established on the complex work condition. It compare the principal stress with the critical stress value by way of measuring the principal stress magnitude, if the principal stress exceed the critical stress value, annunciator will give an alarm. So that the fracture retain on the safety work condition, the structural safety is ensured.
