Abstract:Abstract:MPF (Metal-core Piezoelectric Ceramic Fiber) is a new type piezoelectric ceramic device. The configuration and its response to Lamb-wave fields excited by circular crested actuator are presented in this paper. According to calculating time delays of damage signals with Gabor wavelet transform, MPF sensing single-mode Lamb waves in one-dimensional structural damage localization is investigated. Results show that MPF can be used as the sensor for single mode Lamb wave. The performance of calculating of time delays of damage signals using Gabor wavelet transform is good; the damage localization accuracy is also high.
