Abstract
A fatigue model based on entropy generation is presented and validated through experiments. This model is purely physical and combines statistical mechanics with thermodynamic laws applied at a local scale. The model does not require an empirical damage surface or phenomenological constitutive modeling constants. Damage evolution parameter varies from 0 to 1. As it is for the irreversible internal entropy production, this parameter is a non-decreasing quantity that increases with the degradation of a material.
