Abstract

Angle beam EMATs can transmit ultrasonic waves in oblique directions and detect them in a conductive specimen without any contact. Our FEM simulation verified effects of an internal flaw on receiver signal's peaks shown in our experimental results for a ferromagnetic metal. Visualization of displacement distributions obtained by FEM further showed us how ultrasonic waves propagate a circumference of the flaw.
