Résumé

A thermal model was developed to identify the heat sources accompanying the micro-plastic strains during a cyclic fatigue test. In the first minute of each loading sequence, an infinite bar model allows to defer the consideration of the conductive losses at the jaws. Sources are identified for increasing loading levels, however avoiding to reach the macroscopic plasticity domain.
