Abstract: The tensile tests have been conducted in order to investigate the elastic-plastic strain behavior in thick plate specimens with notches by using strain gages. Especially, the object of this study is to investigate the strain behavior in the center part and the edge part of plate thickness at notch root. From test result, it is found that the axial strain in the center part is larger than one in the edge part with an increase of stress and that the biaxial stress in the center part of plate thickness at notch root develops with an increase of stress. Strain concentration factors obtained experimentally are also compared with estimated values by ASME Code Case N47 method. The correlation between strain concentration factor and plastic zone size or relative plastic zone size are shown.
