unnotched specimens

The steel 50CrMo4 can be assumed to have an S-N curve of the form of Eq. 9.6. Some fatigue test data for unnotched specimens under axial stress, with zero mean stress, are given in Table P9.4.

(a) Plot these data on log–log coordinates, and determine approximate values for the constants A and B.

(b) Obtain refined values for A and B, using a linear least-squares fit to log N f versus log σa. Then calculate  and b for Eq. 9.7.
