摘要：
In this paper we describe the potential of employing the concept of thermodynamic entropy generation to assess degradation in processes involving metal fatigue. It is shown that empirical fatigue models such as Miner's rule, Coffin-Manson equation, and Paris law can be deduced from thermodynamic consideration.
