Examination of structures integrity and failures detection are nowadays of great interest for both civil infrastructure and industry systems. This paper presents Structural Health Monitoring (SHM) technique that was tested on several laboratory models and utilizes elastic wave propagation phenomenon. Furthermore, it describes signals feature extraction procedure by using Principal Component Analysis...
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...
