| Abstract: | In this paper, for the first time, the randomness of fatigue loading,fatigue life and fatiguestrength are definitely c1assified, respectively. Then, several fatigue accumulative damage rules still em-ployed at present are systimatically analysed with respect of the mechanism of mechenics -probability andthe usage range. Two different probabilistic interpretations about fatigue damage accumulation, i. e., thestochastic nature of damage developed in a single individual and the scatter of damage between different in-dividuals in a population, are proposed. In the end, Two-dimensional Probabilistic Miner's Rule is recommended. |
