Notes:
In order to investigate fatigue characteristics of vulcanized natural rubber (NR), fatiguetests are carried out under various stress ratios R (R = minimum stress / maximum stress). It wasconsidered that the fatigue cracks were initiated from flaws in very early stage of total life. Thefatigue damage process was almost the fatigue crack propagation process and it is independent of R.The crack growth rate was proportional to the crack length to about the first power, when the cracklength was defined as the length of the direction perpendicular to the loading direction. Miner’s rulewas examined to observe the fatigue crack behavior and checked by using two-step loading fatiguetests experimentally. It seems Miner’s rule has a possibility to predict fatigue lives
