How to calculate fatigue life

How can I calculate the fatigue life of a variable stress between 0 and 90 MPa in cast aluminum?

Do I use the mean stress and compare it with the wohler curve? what is the logic of using the mean stress? Why not the maximum stress?

Do I have to use the Goodman or Gerber diagram?

Any advise on literature or websites about this topic?

Thank you in advance

Try the Soderberg Line. See Equation 50.31, "Mechanical Engineering Reference Manual for the PE," 10th Edition.
