New functions for description of fatigue curves and their advantages

Popis výsledku v původním jazyce

Two new functions for description of fatigue curves are proposed in the paper: the former (FI) corresponding to Stromeyer function for high-cycle fatigue region, the latter (FII) corresponding to Plmgern function for both low and high-cycle fatiugue regions, i.e. for the whole cycle region from tensile strength to fatigue limit. In comparsion with the functions mentioned above the new functions have many advantages: they allow better fit of experimental results, their parameters have unambiguous physical and geometrical meaning and can be determined with higher accruracy. Both functions are also more suitable for extrapolation and interpolation of fatigue curves in low-cycle and very high-cycle regions. All mentioned advantages are presented in the papaper. No noticeable disadvantages of the proposed functions have been found yet.
