Abstract

A quantitative prediction method for initial crack length in a carbon fibre/epoxy (CF/EP) composites beam using active piezoelectric transducers was established in this study. Wavelet Transform (WT)-based signal processing and identification teclmique in time-frequency domain was developed to facilitate the determination of damage presence and severity. Dynamic response of a CF/EP composites beam containing a continuously expanding crack, coupled with a pair of active piezoelectric disks, was examined under a narrowband excitation, and then applied with the proposed signal processing technique.
