| 摘 要： | 裂纹检测是结构损伤识别的重要研究方向。将裂纹简支梁模拟为由扭转弹簧连接两弹性梁而成的连接体，从而可定量获得可能的裂纹参数。根据裂纹使得局部刚度减小，局部应力集中的现象，分析比较裂纹梁在不同点集中荷载下的最大挠度，定性定位损伤。

| Abstract: | Crack detection is an important research area on Structural Damage Identification.It can obtain the result about the crack parameters quantificationally,by using this system of torsional spring.According to the phenomenon of the decreasing local rigidity and the centralized local stress,we can orient the damage location accurately through analysis comparison about the maximum deflection after concentrated load acting on different points. |
