摘要: We propose the visualization of defects by means guided waves generated simultaneously at multiple frequencies using nonlinearity a high-intensity ultrasonic wave. This report presents use proposed method to visualize slit in thin metal plate. The results confirm that even though multiple-frequency infiltrate defect area different directions, can be visualized imaging wave propagation.
