For effectively detecting the quasi-static component (QSC) of an ultrasonic longitudinal
wave, which is closely related to the elastic nonlinearity of material, we proposed a novel …

Piezoelectric transducer (PT) is the key component in power ultrasonics. Its vibration
amplitude directly reflects the performance of the transducer. The real time measurement of …

Ultrasonic thermal excitation can be regulated by coupling pressure conditions that indirectly
influence the excitation effect. This study evaluated the effects of coupling pressure …

Ultrasonic guided waves (UGW) can be used to inspect and monitor a structure from a single
test location. Piezoelectric transducers are commonly dry-coupled with force to the surface of …

The reliability of structural health monitoring (SHM) systems based on guided ultrasonic
