抄録

The distribution of residual stress in the vicinity of fatigue crack tips and behind them for S15C and SK-5 were measured by X-ray microbeam equipment. Fatigue cracks were loaded and unloaded and then the behaviors of opening and closing were examined analytically. The results obtained are summarized as follows. ( 1 ) A monotonic plastic zone ahead of the crack tip and a cyclic plastic zone was found in the crack tip vicinity. ( 2 ) The ratios of fatigue crack opening and closing found by X-ray measurement were in good agreement with the value found by the microdisplacement method.
