Crack Detection in Multi-Wire Cables Using Guided Ultrasonic Waves
Abstract : Automated Structural Health Monitoring schemes are developed to cost-efficiently prevent failure of mechanical and civil structures, and to predict the structure's residual life. In this work, an efficient crack detection algorithm based on the Hilbert transform is presented. By means of this algorithm, crack localization in multi-wire cables is performed through a time-of-flight analysis of the wave packets. Crack identification can be performed by evaluating the waves' amplitudes. The algorithm is fully automatized and distinguishes between wave packets from different waves independently. Its applicability is analyzed for a single cylindrical wire and for multi-wire cables.
