In this paper, hysteretic energy loss in cyclic loading is used as the main parameter in fatigue
damage modeling. The analytical expression for hysteretic energy loss and its numerical
implementation are features of the powerful hysteretic operator that has the ability to model
progressive damage growth based on the maximum strain amplitude. Its scalar damage parameter
is further modified in order to produce a reliable estimation of fatigue life under arbitrary loading.
