Abstract

Advanced artificial flaw manufacturing method has become available. The method produces true fatigue cracks, which are representative of most service‐induced cracks. These cracks can be used to simulate behaviour of realistic cracks under service conditions. This paper introduces studies of the effects of different thermal loading cycles to crack opening and residual stress state as seen at the surface of the sample and in the ultrasonic signal. In‐situ measurements were performed under dynamic thermal fatigue loading of a 20 mm long artificial crack.
