Identyfikacja uszkodzenia w paśmie aluminium z wykorzystaniem miękkich metod obliczeniowych

This paper presents an application of non-destructive damage detection method based on structural wave propagation phenomenon. A set of laboratory experiments on aluminium strip was carried out. Several failure cases were introduce into the laboratory model. Elastic wave was actuated and received by piezoelements. Recorded signals were processed using wavelet analysis. Obtained signal parameters were used as an input vector of artificial neural networks. Several network architectures were tested.
