Abstract
The majority of mechanical systems can be found in complex environments in which they are causing numerous interferences, generating wear or fractures. Therefore, the use of the Fuzzy Logic technique in the aid of the detection of damages becomes relevant, once this tool can evaluate numerous factors for the real verification of the damage. This contribution uses the eletromechanical impedance-based structural health monitoring method to develop a Fuzzy system capable of identifying structural damages in an aluminum beam. It was measured 300 signatures of impedance for the validation of the model, that presented excellent results, abstracting and identifying the proposed damage conditions.
