M. Kurek et alii, Frattura ed Integrità Strutturale, 41 (2017) 24-30; DOI: 10.3221/IGF-ESIS.41.04 28 Figure 4 : Exemplary analysis of material D30. The hatched field is the area for which the results of the fatigue life are the same or differ insignificantly. Such analysis was performed for all test materials. Fig. 5 shows the distribution of the scatter results for GTS45 material [16]. Figure 5 : Relationship between scatter values T and the angle β for GTS45. The subsequent analysis for exemplary materials is presented in Figs. 6-7. From the analysis of Fig. 7, we can note down that the model also applies to materials, which are not covered by the proposed function (e.g. D30). In the future, it would be necessary to perform a more comprehensive static analysis involving the determination of fatigue characteristics with regard to pure bending and pure torsion for the respective materials.
