In this paper, it is reported that the 2-dimensional curved beams with notch which bottom shape is half circule, are experimented by the photoelastic method on the condition due to bending moment. The experimental values of the maximun stress are measured and the stress concentration factors are calculated which are the ratio of the maximum stress to the nominal stress. The results obtained are as follows: 1) The stress concentratration factors (α_κ) are decreased when the ratio of the depth of notch to the height of beam (d/h) is increased and that facts are considerably on the situation of opposite load than directive load. 2) The factors (α_κ) are decreased the situation of directive load and are increased on the opposite load when radius(R) is increased.
