Abstract

After the basic researches about the cause and the mechanism of nonlinear ultrasound, industrial applications of nonlinear ultrasound have been also expected. Since nonlinear ultrasound requires higher amplitude ultrasound incidence to the crack, we believe that the efficient and reliable transducer must be the key technique to extend nonlinear ultrasound to the industrial crack estimation. In this study, we focused on a new transducer made by PMN-PT single crystal piezoelectric-element that recently developed as an efficient material for an actuator. Furthermore, we tried to use the low-cost burst square pulser to nonlinear ultrasound measurement to spread nonlinear ultrasound technique to many applications by combining with the new efficient transducer.
