In order to obtain correct experimental results, fatigue strength tests carried out on the basis of a measurement setup using dynamic excitation generated by inertial force require test completion criterion to be specified. The paper presents the method applied to identify damage on the basis of an analysis of changes in registered acceleration amplitudes based on experimental studies, and an analysis of image of obtained fatigue fractures.
