We go deep into discussing the studies on structural damage detection based on modal strain energy, and propose a new damage detection index based on the change of modal strain energy ratio.
在此基础上对基于模态应变能的损伤识别方法进行了深入探讨,并提出了基于模态应变能比变化率的损伤识别新指标。
3) Modal Strain Energy Changes Rate
模态应变能变化率
4) ration of the changes of strain modal
应变模态改变率
5) change rate of modal strain
应变模态变化比
6) change rate of the mode shape curvature
模态曲率变化比
1.
Firstly,the change rate of the mode shape curvature was used in the initial location of the joint damage to detect the substructure with damaged joint.
利用模态曲率变化比进行节点损伤的初定位,识别出损伤节点所在的子结构;以此子结构为研究对象,利用杆端应变模态变化比对节点损伤进行准确定位。
补充资料：应变硬化率
strainhardeningrate：表示应变硬化的程度，即表示塑性变形阻力（继续塑性变形所需外应力）随塑性变形量的增大而增加的现象的程度。
