摘要
分析了模态应变能用于结构损伤识别的可行性,并进行了有限元和实验验证.结果表明,模态应变能对损伤较为敏感,能够反映结构的局部状态变化,可以用来检测结构损伤位置.
Mode strain energy is used in the damaged structures; and an experiment is carried out to verify its effciency. The results show that the mode strain energy is very sensitive to the damage of structure and can be used as an indicator in the diagnosis system.
