| 内容記述 | In respect of the improvement of the fatigue strength, it is well known that the plastic prework is effective. But it seems that the effect of the plastic preworking on the fatigue strength and the propagative behavior of the fatigue crack are hardly studied under consideration of mutual relations. Therefore, in this paper, for the plastic torsional preworked circumferentially notched bar of S17C (JIS G 4051), the prework dependence of the fatigue strength under rotary bending tests was studied and that of the propagative behavior of the fatigue crack was discussed by means of the result of Liu's dimensional analysis and stress intensity factor. The following conclusions can be drawn : (1) The suitable plastic torsional prework is effective in increasing the fatigue limit of the smooth and notched specimens, but the excessive preworking tends to decrease it. And the smooth specimen is more effective than notched one in increasing the fatigue limit. (2) The index number of stress intensity factor is from 2.48 to 0.98, and decreases in according to the rate of preworking. (3) The occurence of the fatigue crack is most delayed and the crack propagation speed is the slowest for the notched specimen which is preworked at the nearly most suitable degree in increasing the fatigue limit. |
