Investigation of very high cycle fatigue by thermographyc method
Nowadays, many components and structures are subjected to fatigue loading with a number of cycles higher than 107. In this scientific work, the behaviour of two kinds of tool steel was investigated in very high cycle fatigue regime. The fatigue tests were carried out at the frequency of 20 kHz and...

| description | Nowadays, many components and structures are subjected to fatigue loading with a number of cycles higher
than 107. In this scientific work, the behaviour of two kinds of tool steel was investigated in very high cycle
fatigue regime. The fatigue tests were carried out at the frequency of 20 kHz and in fully reversed tensioncompression
mode (R = -1) by means of an ultrasonic fatigue testing equipment. The radiometric surface
temperature was detected during all the test by means of an IR camera in order to extend the Thermographic
Method and the Energetic Approach in very high cycle fatigue regime. The failure mechanism of the
investigated steels was evaluated by means of several experimental techniques (scanning electron microscopy,
Energy Dispersive X-ray spectroscopy and Optical Microscopy). |
