説明
A report is given at the outset of a modified rotating-bending fatigue testing machine by means of which the specimens can be submitted to programmed alternating stress cycles. The test material is mild steel with 0.47% C which was annealed in vacuum after machining. The results of the tests are reported, of the plain specimens and of four sorts of notched specimens, and the accumulation of the fatigue damage is discussed.<br>It is shown that with the plain specimens and with the blunt notched specimens Miner's hypothesis concerning “linear damage law” that the stress cycles are negligible so far as their amplitude is less than the fatigue limit of the specimen in question could agree with the experimental results. But with the specimens with notches the value of whose stress concentrations factor is larger than 1.8 their fatigue life is found in estimation remarkably critical under “the linear damage law”.
