Determination of fatigue life for low probability of failure for different stress levels using 3-parameter Weibull distribution
P Strzelecki - International Journal of Fatigue, 2021 - Elsevier
This paper presents proposed characteristics of the SN curve using the 2 and 3-parameter
Weibull distribution for fatigue limit and limited life respectively. The parameters of the
proposed model are estimated using the maximum likelihood method. Additionally, it has
presented a method to estimate initial values for the likelihood function. Two applications are
presented, whose SN curves were characterized by using the results for rotary bending of
S355J2+ C and C45+ C steels. The proposed SN curves can be used to determine the …
