A research program was carried out by a group of researchers of nine Italian universities in order to define the fatigue parameters of a commercial steel. The purpose is to define the fatigue limits in different loading conditions and comparing the results obtained by tests performed using different energetic methodologies. In this paper the thermographic method already proposed in literature was performed, determining the Haigh and Goodman-Smith limit curves. At the same time, the thermal response in static tests were derived in order to correlate the limit of the totally thermoelastic behaviour.
