A damage detection technique, which does not rely on any past baseline signals, is
proposed to assess damage in composite plates by using an enhanced time reversal …

Piezoelectric wafer active sensors (PWAS) used in structural health monitoring (SHM)
applications are able to detect structural damage using Lamb waves. PWAS are small …

A structural health monitoring system is developed for continuous online monitoring of
delamination initiation and growth in composite structures. Structural health monitoring …

An analytical investigation of the interaction between piezoelectric wafer active sensor
(PWAS), guided Lamb waves, and host structure is presented in this paper, supported with …

Surface-bonded lead zirconate titanate (PZT) transducers have been widely used for guided
wave generation and measurement. For selective actuation and sensing of Lamb wave …

By use of biaxial stretching process of poly (vinylidene fluoride) fabrication to gain high
