The Ono type bending fatigue limits for usual carbon steel specimens having circular grooves of 0.5mm, 1.0mm and 1.5mm radii are obtained after preworking of statical. tensile, or compressive deformations beyond the yield point. The tensile or compressive deformation produces the work hardening and the residual stress, and the effects of them upon the fatigue limit are studied comparing with the smooth surface and annealed state. The fatigue limits of notched bar with grooves of 0.5mm, 1.0mm and 1.5mm radii decrease by 33%, 34% and 22% respectively as compared with the smooth surface, and are affected similarly both by tensile or compressive deformation. Comparing with annealed state the fatigue limits, obtained after aging of more than a month, fall about 4% for smaller preworking, and then rise by 10-20% for larger preworking. This tendency is similar to that obtained by the work hardening only (2nd report), and the effect of residual stress can not be found. But the effect of the residual stress can be found slightly by the fatigue test carried immediately after preworking. (Received June 19, 1952) |
