Hi, thank you. 

Sorry, but I still haven't understood how I should proceed. If I have three S-N curves, one for zero mean stress, one for a mean stress of 100 MPa, and one for a mean stress of 200 MPa, but the actual mean stress is, for example, 500 MPa, what should I use in the mean stress correction theory: 'none' or one of the theories?
