DETERMINATION OF MICROSCALE ROUGHNESS OF CYLINDRICAL SURFACES USING ULTRASONIC CREEPING WAVES

reportActive / Technical Report | Accession Number: AD0707286 | Open PDF

Abstract:

The circumferential waves or creeping waves propagate in both media separated by a rough interface in an alternating fashion, and are reviewed from a theoretical point of view the associated velocity of propagation dependence on the interface surface roughness is shown to be reasonably valid for microscale roughness determination. Experimental results are also included to support theory, and certain empirical relationships are derived as an example of the application of the technique.
