Abstract
Guided wave is one of the promising non-destructive technologies for detection and identify different types of damages. It can be used to maintain reliable service for damage detection. This study proposes a time-domain spectral element method (SEM) incooperated a crack model for studying guided wave scattering and mode conversion phenomena in pipes. The development of the proposed SEM is based on the elementary rod theory and Timoshenko beam theory. The crack model couples the torsional and flexural motions of guided waves. The results show that there is good agreement between SEM and the experiment measurements.
