This thesis presents an experimental protocol developed to perform complete energy balances during the high cycle fatigue of steels. The aims of this study were to complete and check the infrared image processing used to separately estimate dissipative and thermoelastic sources accompanying the fatigue mechanisms in HCF. This method can work even if the intensities of both heat sources are not in the same order of magnitude. The second purpose was to combine this infrared technique with digital image correlation. These techniques allowed us to locally estimate deformation energy and to compare this with the dissipative energy during a cycle.Cette étude s'inscrit dans une démarche originale consistant à développer un protocole expérimental a...
