Original Abstract

Risk volume can be considered as a volume where the crack will initiate with the highest probability. Thus, it is a serious issue considering the specific geometry of the samples for ultrasonic loading. Also, the distribution of the stresses within the risk volume represents important information for fatigue behaviour prediction and description. The risk volume for 304L stainless austenitic steel samples with different geometry was numerically analysed and correlated to the results of the ultrasonic fatigue experiments. Obtained fatigue data and the evolution of the microstructure related to the calculated risk volume sizes. The formation of slip marks corresponded to the calculated stress distribution within the risk volume. The differences in the calculated sizes of the risk volume for different sample geometries were reflected in changes in the microstructure of the material and in the measured fatigue lifetimes. Obtained results can partially explain observed differences in the fatigue properties when comparing ultrasonic fatigue testing with conventional methods.
