An Ultrasonic Guided Wave Mode Excitation Method in Rails

open access: yesIEEE Access, 2018
This paper proposes a new method for exciting a specific mode of guided ultrasonic wave in a rail. The method requires the cross-sectional mode shape to determine excitation direction, excitation coefficient, and excitation position of each mode. The cross-sectional mode shape data of all modes are acquired by the semi-analytical finite element (SAFE ...
