SN assumes that all stresses remain elastic throughout the loading history.  It assumes that no plastic deformation occurs.  However, it is used sometimes used with elastically calculated stresses in applications where some plastic deformation occurs in the early cycles, but the behavior “shakes down” to elastic behavior after a few cycles.

EN is applicable to elastic or plastic stresses throughout the loading history.
