Fatigue limits of leaf springs

  1. Mar 8, 2012 #1
    Hi to all.

    How would I go about calculating the fatigue limit of leaf springs?

    Is there an equation out there in the form of

    N, cycles to failure= f(variables, material properties)

    Or will I have to use the Stress equations for leaf springs and use that stress value and
    then look up a S-N curve for that particular material??

    Tnx in advance.

    There are no shortcuts in this life. You will have to use the stress equations for the springs and then use those stresses in the S-N curve for the material. That's what you'll be getting the big bucks to do!
