EXAMINATION OF STRUCTURES BY MEANS OF FATIGUE TESTS AND VIBRATION TESTS AT RESONANCE. REPORT OF ENQUIRY

This report contains a survey on the strains to which a component is exposed in service, on the fatigue of materials on their endurance, on the determination of the permissible stresses and on the influence of the various factors on fatigue. After having recalled the various types of testing machines the report gives a brief description of a certain number of resonant fatigue testing machines, the control of the machines and the opportuneness of the programmed tests. The conclusions resulting from the study are the following: Resonant fatigue tests are currently applied both in industrial and in railway operation fields. The designation "resonant fatigue tests on components" is a conventional one, because, in reality, the tested component is exposed to stresses at frequencies different from the natural resonant frequencies actually encountered by the in service.
