Enhancement of ultrasonic surface waves at wedge tips and angled defects Enhancement of ultrasonic surface waves at wedge tips and angled defects
The behaviour of sound waves interacting with wedges has attracted interest from researchers in geophysics and non-destructive testing. We consider here the nearfield behaviour of Rayleigh waves incident on wedges and surface-breaking defects which propagate at an angle to the surface, such as rolling contact fatigue on rails. It has been shown that, for a detection point on the edge of the cra...
متن کاملAir coupled ultrasonic detection of surface defects in food cans
In this paper we describe an ultrasonic inspection system used for detection of surface defects in food cans. The system operates in pulse-echo mode and analyzes the 220 kHz ultrasonic signal backscattered by the object. The classification of samples into valid or defective is achieved with χ statistics and the k-nearest neighbour method, applied to features computed from the envelope of the ul...
متن کاملPhase changes of ultrasonic surface and bulk waves through focusing measured using non-contact ultrasonic methods
Focusing an ultrasonic surface or bulk wave to a point can maximise the amount of ultrasonic energy at a point and increase the sensitivity of a measurement. Using noncontact ultrasonic methods we focus an ultrasonic wave pulse on or in a sample. Focusing can be achieved by using a shaped source or by the surface profile of the sample itself. Experiments and modelling confirm the known result t...
متن کاملUltrasonic scaler oscillations and tooth-surface defects.
Damage to tooth root surfaces may occur during ultrasonic cleaning with both piezoelectric and magnetostrictive ultrasonic scalers. It is unclear which mechanism causes more damage or how their mechanism of action leads to such damage. Our null hypothesis is that tooth-surface defect dimensions, resulting from instrumentation with ultrasonic scalers, are independent of whether the scaler probe ...
متن کاملGuided Wave Non-contact Ultrasonic for Nde
Non-contact ultrasonic, enables rapid testing of structures using ultrasonic tests that are not possible via conventional contact transducers. This paper reports on laser ultrasonic and air/gas coupled ultrasonic measurements that are performed remotely, do not require direct access to test area, do not need traditional ultrasonic coupling and do not have traditional C-scan fixture requirements...
