The Analysis of Mechanism for Generating and Detecting Torsional Guided Wave

Abstract:

The T(0,1) mode guided wave is widely used in long term NDT of the pipelines. The magnetostrictive transducer for generating and detecting guided wave is important to long term NDT of the pipelines because the transducer is compact and can be used at high temperature. The paper explains the mechanism of the generation and detection of T(0,1) mode guided wave in magnetostrictive strip based on Wiedemann effect. The experiment with MSGW is done to confirm the mechanism in a aluminum pipe.
