A typical out-of-phase TMF test (with temperatures varying from 250 to 450 Celsius) is shown in figure 19. All these in-phase and out-of-phase tests are used to calibrate the parameters of the plasticity and the DTMF models. In this study the material properties of SIMO 4.06 have not been calibrated (from available data) but rather adopted from [19].

Figures 20 to 22 and Tables 1 show the material properties of SIMO 4.06, used in the present study. The literature is scarce in TMF material properties as the tests are expensive and time consuming. The author doesn’t have permission to share the DTMF properties adopted in the present study, but only the fatigue results from the performed analyses.
