Uma contribuição aos sistemas de monitoramento de integridade estrutural aplicada a estruturas aeronáuticas e espaciais

Abstract

This work presents a contribution to SHM (Structural Health Monitoring) techniques devoted to aircraft and space components. This way, it intends to present some fields of application of the above mentioned techniques that have not yet been sufficiently explored, such as simple mechanical structures, methodologies of coupling web technologies and online structural monitoring and storage of information in data bases. Besides, recent SHM techniques (Lamb Waves and Electromechanical Impedance) are applied to various types of real structures under a practical viewpoint, aiming at real engineering applications. It is important to take into account that due to the absence of precise numerical methods, the presented studies are based on an experimental approach, using innovation techniques, artificial intelligence methods, signal analysis, statistics and client-server programming through internet. Finally, the obtained results demonstrate the potential use of the cited SHM techniques together with reliable mathematical and computational methodologies.
