| 内容記述 | The effect of torsional prework on the fatigue strength and crack growth for smooth specimen is compared with the previous results for notched specimen in plane carbon steel. A theoretical reduction factor, which denotes the decreasing extent of the crack growth rate arisen from the prework, is introduced by taking the hysteresis loop near the crack tip into account, and compared with the experimental one. The fracture surfaces are observed under a scanning electron microscope. The following conclusions were obtained; (1) The rate of increase in the fatigus strength with the extent of prework is greater for the smooth specimen than for the notched one. (2) Under the same stress intensity factor, the crack growth rate for the smooth specimen is greater than that for the notched one in relatively low ranges of the extent of prework, but at or near some degree of prework which the fatigue strength is reversed in order each other, this behavior of the crack growth is reversed, too. (3) The theoretical reduction factor fairly coincides with the experimental result in relatively low ranges of the extent of prework. (4) The typical fracture markings such as striation, quasi-striation, tire track and so on are observed for all the preworked specimens. |
