Question: A 5160H steel was tested in fatigue and the distribution
A 5160H steel was tested in fatigue and the distribution of cycles to failure at constant stress level was found to be n = W [36.9,133.6, 2.66] in 103 cycles. Plot the PDF of n and the PDF of the lognormal distribution having the same mean and standard deviation. What is the L10 life (see Prob. 20–19) predicted by both distributions?
