Last updated on 02 December 2013 4:40
The non destructive determination of crack length in fatigue and fracture mechanics investigations is frequently carried out using a.c. or d.c. potential drop systems. An alternative method using ultrasonic surface waves which has features in common with a.c. potential drop has teen investigated.
