Abstract
This work concerned the study and the development of a health monitoring system for aeronautical applications. This system was based on the generation and sensing of Lamb waves in composite structures by thin piezoelectric transducers that were surface bonded. In order to optimise such a system, a hybrid modelling technique was used to conceive transducers better adapted to Lamb waves generation. The technique was successfully applied in the selection of a Lamb-mode that was sensitive to damage
