Abstract: A nondestructive method that evaluates the distribution of plastic strain using an ultrasonic wave would be useful for estimating a structure's state prior to crack development. The authors have proposed an ultrasonic wave measurement method by combining an EMAT and PVDF, in which the couplant is not needed if a contact-type PVDF sensor is used. This paper reports on the comparison and examination of adhesion-type and contact-type PVDF sensors combined with an EMAT for ultrasonic wave transmission.
