User-defined E-N curve

A user-defined E-N curve is a strain-based life criterion where you specify a table that relates maximum principal strain amplitudes, , to a corresponding number of reversals to failure, 2Nf:

The function f is the table of the user-defined E-N curve that you specify for the material.

The mean stress effect and biaxial fatigue cannot be included with user-defined E-N curves.
