FDS is a concept introduced to explain the fatigue accumulation due to vibration. There are many assumptions in the process of derivation of formulas, so there is not a single result, and there are various approaches depending on the situations and various results therefrom. Therefore, it is desirable to understand the derivation process and its theoretical background in order to synthesize the vibration test using FDS or to predict the remaining life. In this paper, from the perspective of ERS to FDS, the theoretical background and the derivation process of mathematics were examined from various perspectives through literature review.
