Research Abstract

In this research, for smart metallic and composite structures with sensor and actuator network in operating aircrafts and high speed vehicles, a highly accurate numerical simulation method of Lamb wave propagation and a signal processing method have been developed. Based on detailed investigations of interactions between Lamb wave and various damages, the mechanism of reflected and transmitted waves, and the characteristics of these reflected and transmitted waves have been studied. Then, the identification accuracy and reliability of damage location in metallic and composite structures has been improved, moreover, quantitative evaluation methods of damage size have been built up.
