A new function for fatigue curves characterization and its multiple merits

Multiaxial high-cycle fatigue criteria and life prediction: Application to gas turbine blade

“…Since fatigue test results are widely scattered especially for HCF region, several probabilistic models were available in the literature to estimate the S-N curve considering its scatter [23,24]. In this section, and for each loading configuration, stress life curves were simulated using the Stromeyer, Palmgren and Bastenaire models [25] . For both reversed and repeated bending, the Stromeyer model Eq.…”

Evaluation of fatigue life of AZ31 magnesium alloy fabricated by squeeze casting

“…12. Experimental data in the low and high-cycle fatigue regions were fitted by the Stromayer (8) and the Kohout-Věchet (K-V) functions (9) [18]. The regression parameters are summarized in Table 6.…”

Application of new damage indicator-based sequential law for remaining fatigue life estimation of railway bridges

“…In the case of sequential law it is essential to know the Wöhler curve for full range of the number of cycles. Therefore the chosen partially known Wöhler curve, which is mentioned under the UK railway assessment code [11], was transferred to fully known Wöhler curve by using Kohout and Vechet Wöhler curve modelling technique [12]. The obtained function and the geometrical shape of new fatigue curve, which corresponds to class WI riveted connection, are illustrated in Fig.…”

“…Further, it describes only the behaviour of wrought iron and does not represent any riveted feature of a wrought iron connection. The mathematical expression for the test curve has been obtained by using the Kohout and Vechet fatigue curve modelling technique [12] and the obtained expression with geometrical shape of the curve is illustrated in Fig. 7 (the top curve: predicted fatigue curve from rotating bend test data).…”
