Flat bar specimens of Epoxy Resin with two U notches of identical shape on one edge were subjected to pure bending. The effects of the pitch of two notches, the notch depth and also the root radius on the stress concentration factors were investigated. As to the effect of the pitch, the stress concentration factor of two notches decreased first owing to the overlapping effect, and then showed an increase up to the value of a single notch. With respect to the effects of the notch depth and the root radius, the stress concentration factor of two notches showed a similar change to that of a single notch. In all cases examined, the stress concentration factors of two notches obtained were smaller than those of a single notch. This fact offers a possibility of reducing the stress concentration due to a single notch by a supplementary notch formed in its neighbourhood.
