| 内容記述 | When many stress concentrated parts exist closely, a different fatigue behavior pattern is revealed due to their interaction than that shown by a single part. The effect of interaction of notches on fatigue strength was investigated regarding the effect of the number of notches by the round bar speciment of S35C, with multiple 60°-V notches subjected to rotary bending. The results are obtained summarized as follows; 1) The stress concentration factor decreased by increasing the number of notches, and it approached a constant value. In relation to this tendency, both the fatigue limit for crack initiation σ_{w1} and the fatigue limit for failure σ_{w2} increased gradually with the number of notches, and both also approached constant values, respectively. 2) The σ_{w1} showed fluctuation depending on whether or not the number of notches were odd or even, and wherther the notch root radius at the ''branch point'' differed from the odd or even number of notches. These results suggested that some stress factors other than the maximum stress at the root of the notch governed the crack initiation and propagation. 3) The length of the non-propagation crack became shorter with an increase in the number of notches. | |||||||||||||||||
