The evaluation of the temperature rising during a fatigue test is extremely important to define the energy method to use. In order to define the best load program and the more appropriate test frequency, it is necessary to estimate the surface temperature of the material, in particular when it needs to arrange some tests on mechanical components. In the past the internal damping factor was considered an important parameter to define the fatigue quality of the steel used for the mechanical application but another important parameter is linked to the plastic strain caused by the high number of fatigue tests. It is proposed also a model for the estimation of the crack propagation during the last cycles of fatigue test.
