Surface crack monitoring by Rayleigh waves with a piezoelectric-polymer-film ultrasonic transducer array

Surface crack monitoring by Rayleigh waves with a piezoelectric-polymer-film ultrasonic transducer array

This paper presents a method for measuring surface cracks based on the analysis of Rayleigh waves in the frequency domain. The Rayleigh waves were detected by a Rayleigh wave receiver array made of a piezoelectric polyvinylidene fluoride (PVDF) film and enhanced by a delay-and-sum algorithm. This me...
