| 1. | This study presents a preliminary study on the piezoelectric - based built - in structural health monitoring system which can be integrated seamlessly into the composite structure . a damage detection and identification method using lamb waves and time - frequency analysis is proposed for continuously monitoring of composites , detecting the damage in near real - time , localizing it accurately , sizing it approximately and visualizing it finally . in this study , lamb waves propagating in anisotropic laminates are first modeled analytically using higher - order plate theory and the direction - dependent dispersion relations of the waves are established
本文对能无缝集成在复合材料结构中的基于压电传感网络的嵌入式结构健康监测系统进行了研究,提出将瞬态应力波( lamb波)和先进数据处理方法(小波分析)相结合的方法,对复合材料结构进行在线的连续监测,近乎实时地检测出损伤的发生,准确判定损伤的位置,估算出损伤的程度,并将这些结果和信息可视化。 |
