| 内容記述 | It has been recognizd that a series of closely spaced notches represnts lower degree of stress concentration than that of a single notch. As the first step, to obtain information for the fatigue strength in such a case, we studied following experiments ; (1) The stress concentration factor of flat bar specimene of Epoxy Resin with one or tow 60°-V notches of identical shape on both edges subjected to pure bending, was measured by the photo elastic method varying the root radius of notches. (2) We measured the fatigue strength of shaft of the carbon steel for machine structural use, S35C, with one or two 60°-V groove notches subjected to rotary bending. The results obtained are summarized as follows ; (1) The experimental values of stress concentration factor for a single notch are almost coincident with Neuber's theoritical ones. (2) In computing the stress concentration factor, we suggest to use the effective notch depth at the end notches instead of actual notch depth, and obtained good results. (3) The root radius of notch at the branch point, ρ_0 is nearly 0.4~0.5mm for the tow notch specimens as single ones. (4) The fatigue crack initiated at a point of maximum stress, slightly out of the notch bottom. |
