抄録: The plane bending tests have been conducted in order to investigate the elastic-plastic strain concentration factor and plastic zone sizes in plate specimens with notches by using strain gages. From test result, we show the relation between the multiply of the strain concentration factor by the stress concentration factor and the bending stress, and compares these result with Neuber's equation. Strain concentration factors obtained experimentally are also compared with estimated values by ASME Code Case N47 method. The relations between strain concentration factor and plastic zone size or relative plastic zone size are shown. It is found that the estimated values of strain concentration factor are larger than the experimental values. It is also found that the relationship between strain concentration factor and plastic zone size becomes linear respectively each notch root radius. It is found that both maximum strains at both sided notches do not coinsides each other due to yield.
