Anotace knihy

The work encompasses a study of interaction between §embedded PZT transducers and composite structures as §well as technique improvement to simplify Lamb waves §analysis. The design of embedded PZT transducers was §improved by reducing the stress concentrations in §composites. The experiments, performed in static §loading, indicated that the embedded PZT transducer §did not significantly reduce the strength of the §composite. Further investigations were conducted to §evaluate the performance of the improved PZT §transducer used as a Lamb wave generator embedded in §composites subjected to mechanical loading. The §tests were performed in static and fatigue loading. §The study showed a large working range of the §embedded PZT transducers. A post processing §technique based on wavelets was developed for damage §assessment. This method focused on the wavelet §coefficients from the Lamb wave response §decomposition, improving the damage detection §capabilities. The other technique was devoted to §filtering the Lamb waves by the use of multi-element §transducers. This technique allowed the reduction of §the effect of a Lamb wave mode towards another
