 note = {The behavior of fatigue crack propagation of round bar specimens of S35C with one to three sharp notches was investigated and the results obtained are summarized as follows; 1) Crack length at notches that did not fracture increased with the overstress ratio and saturated at some ratio. 2) The ratio of the crack propagation period in the total fatigue life was estimated to be about 98%, regardless of the number of notches and applied stress. 3) The behavior of crack propagation on specimens with two and three notches was found to be explained well with stress intensity factors accounting for interaction between notches by the principle of superposition.},
