Timefrequency beamforming for nondestructive evaluations of plate using ultrasonic Lamb wave
Timefrequency beamforming algorithms are proposed for structural damage detection. They are to suppress the effects of excitation- and boundary-induced waves. Experimental data are obtained with an aluminum panel. The experiment data are used to validate the proposed beamforming approaches.
