小损伤 meaning in English

microlesion

The method of forming small damage fem in ansys
如何高效建立小损伤振动模型
Eigenvalue perturbation theory with applications to small structural damage detection
特征值摄动法在利用动响应结构小损伤检测中的应用
The application of the three damage identification techniques above for simple supported beams and cantilever beams confirm that vague or wrong location will occur in the damage location method based on flexibility difference , and the curvature modal method need not rely on the structural parameter before the damage , but has the hidden trouble of vague location for small damage
将以上三种损伤识别技术应用于简支梁、悬臂梁的模拟损伤识别，证实了基于柔度差值的损伤定位方法存在模糊或者错误定位的问题，曲率模态法可以不依赖损伤前的结构参数，但对于小损伤也存在模糊定位的隐患。
