Abstract

An innovative coupling method is presented that significantly improves the distribution of ultrasonic energy of guided waves for vibrothermography non-destructive testing. While typical sources radiate ultrasound cylindrically from the point or area of contact, it’s possible to channel energy towards a specified direction, e.g. the field of view of an infrared camera, by placing periodic linear structures between the transducer and the specimen. Their distance is phase matched to the wavelength of the guided wave excited that is determined by the excitation frequency and specimen properties. This antenna-like coupling device works exceptionally well in conjunction with the local defect resonance technique, as both techniques require a frequency dependent set-up. A significant increase in the defect vibration amplitude was measured when using this ultrasonic line source. Likewise, vibrothermography testing results confirm that channeling ultrasonic energy towards a specified direction is advantageous for exciting defect vibrations while using low energy input sources.
