Abstract

The purpose of this paper is to analytically explore that an electromagnetic ultrasonic transducer (EMAT) can be used to do the activity determination of crack defects. Acoustic emission (AE) testing has been done through the innovative use of EMAT, and the activity of defects can be determined based on the Kaiser effect. In consideration of the Lorentz force and magnetostrictive force, the magnetism, force, and vibration displacement of aluminum sheet and steel sheet are analyzed through the finite-element method and fast Fourier transformation. The db3 wavelet is used to obtain the rule of signal change with excitation current. The experimental system of aluminum sheet and steel sheet was established for verification. This method effectively expands the AE theory based on global loading and also gives full play and expands the defect detection capability of EMAT equipment.
