A novel approach to the estimation of strain life fatigue parameters

A method of predicting cyclic stress–strain curve from tensile properties for steels

“…Basan et al [8] investigated correlations between experimentally determined cyclic deformation properties and hardness of quenched and tempered low-alloy steel 42CrMo4. Experimental data from forty 42CrMo4 steels gathered from the literature and their own test results were used to obtain the correlations.…”

“…No correlation could be found between the cyclic strain hardening exponent and hardness, so the median value of n 0 ¼0.1087 was used to represent this parameter [8].…”

“…(6) [7] based on K and from Eq. (7) [8] based on HB, as well as Eqs. (14a), (14b), (15a), and (15b) are compared in Table 3.…”

“…These methods along with the methods from [7] and [8] are compared in Table 4. From comparison of values in Table 4 it can be seen that the prediction methods based on Eqs.…”

Fatigue Life Assessment of Selected Engineering Materials Based on Modified Low-Cycle Fatigue Test

“…The results of some studies prove a classic approach to the determination of fatigue characteristics when based on HCF and LCF tests. In recent years, studies have also appeared that attempt a different approach to the determination of the fatigue life of materials/products [10,11], including those based on hardness testing [12] or applying the idea of neural networks [13,14].…”
