구조물 손상진단을 위한 Lamb 파의 시간-역전현상에 대한 실험
Experiment on the Time-Reversal of Lamb Waves for the Application to Structural Damage Detection
- 발행 : 2007.11.08
초록
In this paper, the possibility of time reversal phenomenon was investigated in damage detection of structure. In conventional lamb wave techniques, damage is identified by comparing the measured data (baseline signals) and the current data. But this method can lead to high false signal in the intact condition of structures due to environmental conditions of the structures. So in this studying, we investigate the possibility of damage detection in the aluminum plate using the time reversal phenomenon of lamb waves.
