RAYLEIGH-WAVE DIFFRACTION IN ULTRASONIC TESTING OF CHEMICAL PLANT

摘要

Experimental results are described that serve to improve methods of ultrasonic monitoring for engineering components. Observed relationships are obtained for the reflection coefficient R and transmission coefficient D and for the sum R~2 + D~2 as a function of the depth of extended crack models for ultrasonic piezoelectric detectors with Ravleigli angles for the prism under various irradiation conditions.
