In this paper, 3-dimensional fracture phenomena in the local area near a through notch tip located between the surface and the canter were investigated by using embedded dyeing grids with the pitch of 50.8㎛. It was confirmed that displacement V and square root of distance from notch tip y½are not proportional in the local area of √|y|<0.3㎜½and the maximum shear strain εxymax near a notch tip occurred at the curvature beginning point of the notch curve. It was also noted that the maximum strain εmax in the thickness direction occurred at the interior, where the ratio of the distance measured from surface to the half of thickness of specimen is 0.3.
