AN EVALUATION OF ULTRASONIC PROBES BY THE PHOTOELASTIC VISUALISATION METHOD

An assessment of ultrasonic probe performance is described in which ultrasonic waves have been visualised by the photoelastic method. A qualitative examination of selected compressional, shear and Rayleigh wave probes has been produced. Ultrasonic wave generation and wave interactions with artificial and "natural" defects in glass testpieces are displayed. In addition the practicability of quantifying ultrasonic wave stresses has been demonstrated. Based on this examination the optimization of probe design in particular cases has become possible. Solutions to ultrasonic inspection problems within the railway industry are reviewed in which specially designed ultrasonic probes are employed. In particular the examination of axles and rails are discussed in which a variation in probe design was necessary due to features of defect orientation.
