Based on nine experimental fatigue tests, 24 virtual constant amplitude tests (CAT) were calculated for each of four stress amplitudes using the accelerated lifetime prediction method StressLife. To expand the experimental database, four additional experimental CATs were conducted at each of two stress amplitudes. The virtual CATs were validated
The fatigue behavior of unnotched and notched specimens of the SAE 1045 streel in normalized condition differs significantly in terms of the nominal stress. As the notch factor increases, the nominal stress decreases considerably. This shows the influence of the notch effect on fatigue behavior.
Utilisation of statistical approaches within the scope of lifetime prediction methods for notched specimens using the example of unalloyed steels
The construction of dynamically loaded metallic materials and components is usually based on the relation between the stress amplitude and the number of cycles to failure, which is displayed in S-N curve
