Flat bar specimens of Epoxy Resin with multiple V notches of identical shape formed on one edge were subjected to pure bending. The effect of the pitch on the stress concentration factor of each of the multiple notches was investigated, the depth of the notch being varied in three steps. In the range of smaller pitches, the reduction in stress concentration due to the overlapping effect was observed quited similarly to the case of the previous experiment on two notches, but its amount was found different between the central, intermediate and outside notches. As to the effect of the notch depth, an optimum depth was found to exist. For multiple notches with more than five, the stress concentration factors of both the central and outside notches showed nearly constant values.
